It is very important for tsunami early warning systems to provide inundation predictions within a short period of time. Inundation is one of the factors that directly cause destruction and damage from tsunamis. This research proposes a tsunami impact prediction system based on inundation data analysis. The inundation data used in this analysis were obtained from the tsunami modeling called TsunAWI. The inundation data analysis refers to the coastal forecast zones for each city/regency that are currently used in the Indonesia Tsunami Early Warning System (InaTEWS). The data analysis process comprises data collection, data transformation, data analysis (through GIS analysis, predictive analysis, and simple statistical analysis), and data integration, ultimately producing a pre-calculated inundation database for inundation prediction and tsunami impact prediction. As the outcome, the tsunami impact prediction system provides estimations of the flow depth and inundation distance for each city/regency incorporated into generated tsunami warning bulletins and impact predictions based on the Integrated Tsunami Intensity Scale (ITIS-2012). In addition, the system provides automatic sea level anomaly detection from tide gauge sensors by applying a tsunami detection algorithm. Finally, the contribution of this research is expected to bring enhancements to the tsunami warning products of InaTEWS.

Recent observations of the coastal impact of large tsunamis (e.g., Indian Ocean 2004; Tohoku 2011) and related numerical and theoretical works have made it increasingly clear that tsunami waves arrive nearshore as a series of long waves (so-called N-waves) with, often, the superposition of undular bores around each crest. Such wave trains are much more complex and very much in contrast with the solitary wave paradigm which for a long time was the accepted idealization of tsunami waves in both experimental and numerical work. The dissipation associated with these breaking bores can be very large, particularly over a wide and shallow continental shelf such as along the east coast of North America, particularly for the shorter waves associated with tsunamis generated by Submarine Mass Failures (SMFs). In this paper, we perform numerical simulations of tsunami coastal impact in the context of both idealized laboratory experiments and several tsunami case studies. We attempt to clarify the key physical processes at play in such cases, and discuss the parameterization of long wave dissipation and implications for models of coastal tsunami hazard assessment.

Abstract. Indonesia has experienced several tsunamis triggered by seismic and non-seismic (i.e., landslides) sources. These events damaged or destroyed coastal buildings and infrastructure and caused considerable loss of life. Based on the Global Earthquake Model (GEM) guidelines, this study assesses the empirical tsunami fragility to the buildings inventory of the 2018 Sunda Strait, 2018 Sulawesi–Palu, and 2004 Indian Ocean (Khao Lak–Phuket, Thailand) tsunamis. Fragility curves represent the impact of tsunami characteristics on structural components and express the likelihood of a structure reaching or exceeding a damage state in response to a tsunami intensity measure. The Sunda Strait and Sulawesi–Palu tsunamis are uncommon events still poorly understood compared to the Indian Ocean tsunami (IOT), and their post-tsunami databases include only flow depth values. Using the TUNAMI two-layer model, we thus reproduce the flow depth, the flow velocity, and the hydrodynamic force of these two tsunamis for the first time. The flow depth is found to be the best descriptor of tsunami damage for both events. Accordingly, the building fragility curves for complete damage reveal that (i) in Khao Lak–Phuket, the buildings affected by the IOT sustained more damage than the Sunda Strait tsunami, characterized by shorter wave periods, and (ii) the buildings performed better in Khao Lak–Phuket than in Banda Aceh (Indonesia). Although the IOT affected both locations, ground motions were recorded in the city of Banda Aceh, and buildings could have been seismically damaged prior to the tsunami's arrival, and (iii) the buildings of Palu City exposed to the Sulawesi–Palu tsunami were more susceptible to complete damage than the ones affected by the IOT, in Banda Aceh, between 0 and 2 m flow depth. Similar to the Banda Aceh case, the Sulawesi–Palu tsunami load may not be the only cause of structural destruction. The buildings' susceptibility to tsunami damage in the waterfront of Palu City could have been enhanced by liquefaction events triggered by the 2018 Sulawesi earthquake.

Abstract_ The increasing of tsunami event has called the integration of urban design for disaster impact mitigation. The Geodynamics position of many global cities puts latter areas are highly vulnerable to earthquake followed by tsunamis. In supporting its function as the main hub in social and economic and protecting environment, the employment of urban design for tsunami impact mitigation is hypothesized as sustainable mean. Therefore, this paper seeks the possibility of employment of urban design’s physical element for tsunami impact mitigation within disaster studies field using literature and case studies for Indonesian cities context. This study recommends that Infrastructure planning and design, Coastal forest, Early warning system, Emergency road network planning, Pre-tsunami evacuation planning and Building design and construction are suitable physical element for impact mitigation.

Submarine slides can trigger tsunamis with high affecting offshore structures, subsea facilities and human lives along the shoreline. Unfortunately, slide-generated tsunami is a difficult problem due to the source of sliding of mass failure by itself or by the other earthquakes. There are no effective numerical model that could simulate simultaneously all stages of generation, propagation, run-up and impact of tsunami phenomena. Physical understanding of slide tsunami hazards is very poor. We must understand substance of tsunami clearly and how to find methods to reduce damage from tsunami wave. This paper will present a parallel computing based on ParallelSPHysics, it can simulate a comprehensive model of tsunami wave by using Smooth Particle Hydrodynamics method.

Abstract. On 22 December 2018, a tsunami was generated from the Mount Anak Krakatau area that was caused by volcanic flank failures. The tsunami had severe impacts on the western coast of Banten and the southern coasts of Lampung in Indonesia. A series of surveys to measure the impacts of the tsunami was started 3 d after the tsunami and lasted for 10 d. Immediate investigations allowed the collection of relatively authentic images of the tsunami impacts before the clearing process started. This article investigates the impacts of the 2018 Sunda Strait tsunami on the affected areas and presents an analysis of the impacts of pure hydrodynamic tsunami forces on buildings. Impacts of the tsunami were expected to exhibit different characteristics than those found following the 2004 Indian Ocean tsunami in Aceh. Data were collected from 117 flow depths along the Banten and Lampung coasts. Furthermore, 98 buildings or houses were assessed for damage. Results of this study revealed that the flow depths were higher in Banten than in Lampung. Directions of the tsunami arrays created by the complex bathymetry around the strait caused these differences. Tsunami-induced damage to buildings was mostly the result of impact forces and drag forces. Damping forces could not be associated with the damage. The tsunami warning system in Indonesia should be extended to anticipate non-seismic tsunamis, such as landslides and volcanic processes driven by tsunamis. The lack of a tsunami warning during the first few minutes after the generation of the first wave led to a significant number of human casualties in both of the affected areas.

When a cosmic object strikes the Earth, it most probably falls into an ocean. Depending on the impact energy and the depth of the ocean, a large amount of water is displaced, forming a temporary crater in the water column. Large tsunami-like waves originate from the collapse of the cavity in the water and the ejecta splash. Because of the far-reaching destructive consequences of such waves, an oceanic impact has been suggested to be more severe than a similar-sized impact on land; in other words, oceanic impacts may punch over their weight. This review paper summarizes the process of impact-induced wave generation and subsequent propagation, whether the wave characteristic differs from tsunamis generated by other classical mechanisms, and what methods have been applied to quantify the consequences of an oceanic impact. Finally, the impact-induced tsunami hazard will be evaluated by means of the Eltanin impact event.

This paper reviews methods applicable to assess the impact of tsunami forces on coastal structures. Countries affected by tsunamis have proven that this environmental disaster has costed billions of losses, such as the event occurred during year 2004 Andaman tsunami. Therefore, there is a need to assess the structural behaviour upon the impact of tsunami forces in order to minimize the damages and to ensure that coastal structures are able to sustain loading from high current-velocity waves. Currently in practice, there are two approaches of accessing the impacts of tsunami on structures namely physical modelling and experiment or numerical modelling and simulation. Numerical modelling methods are expected to produce acceptable analysis on the stability and condition of structures subjected to tsunami loadings since it incorporates several important parameters which are not implemented in physical modelling. The result from this study is expected to prompt engineers and relevant authorities to revise the current design guidelines on coastal structures which could sustain possible tsunami event in the future.

Each year, about 60 000 people and $4 billion (US$) in assets are exposed to the global tsunami hazard. Accurate and reliable tsunami warning systems have been shown to provide a significant defence for this flooding hazard. However, the evolution of warning systems has been influenced by two processes: deadly tsunamis and available technology. In this paper, we explore the evolution of science and technology used in tsunami warning systems, the evolution of their products using warning technologies, and offer suggestions for a new generation of warning products, aimed at the flooding nature of the hazard, to reduce future tsunami impacts on society. We conclude that coastal communities would be well served by receiving three standardized, accurate , real-time tsunami warning products, namely (i) tsunami energy estimate, (ii) flooding maps and (iii) tsunami-induced harbour current maps to minimize the impact of tsunamis. Such information would arm communities with vital flooding guidance for evacuations and port operations. The advantage of global standardized flooding products delivered in a common format is efficiency and accuracy, which leads to effectiveness in promoting tsunami resilience at the community level.

Tsunamis are rare events compared with the other natural disasters, but once it happens, it can be extremely devastating to the coastal communities. Extensive inland penetration of tsunamis may cause the difficulties of understanding its impact in the aftermath of its generation. Therefore the social needs to technologies of detecting the wide impact of great tsunamis have been increased. Recent advances of remote sensing and technologies of image analysis meet the above needs and lead to more rapid and efficient understanding of tsunami affected areas. This paper provides a review of how remote sensing methods have developed to contribute to post-tsunami disaster response. The evaluations in the performances of the remote sensing methods are discussed according to the needs of tsunami disaster response with future perspective.

Lors du tsunami de Tohoku en 2011, des relevés de terrain sur les côtes japonaises ont montré la fragilité des structures côtières, où le plus grand brise-lames du monde (brise-lames de Kamaishi) a été fortement endommagé dû à cet événement. Dans ce doctorat, l'objectif est d'étudier l'interaction entre les brise-lames , les structures côtières les plus communes protégeant les zones urbaines et les entrées des ports, et les vagues, en particulier les tsunamis.Dans la première partie de ce travail, la transformation du tsunami en bore ondulaire dans les zones côtières est étudiée numériquement avec le code de calcul BOSZ (modèle Boussinesq). Les résultats montrent que la deuxième vague générée par le tsunami de Tohoku s'est transformée en un bore ondulaire. En revanche, la première vague n'était pas assez cambrée pour permettre une telle transformation. Les forces et les moments dus aux vagues ainsi que la contrainte normale appliquée par la base arrière du caisson sur le sol de fondation sont calculés à l'aide de deux modèles numériques différents: BOSZ et THETIS (modèle Navier-Stokes). Les résultats de BOSZ sont comparés avec THETIS pour l'interaction tsunami-structure. L'étude d'impact est réalisée à relativement grande échelle dans le but d'obtenir une première estimation des efforts d'un tsunamiPar la suite, une expérience numérique utilisant le modèle THETIS a été réalisée pour étudier les impacts du type flip-through sur des brise-lames. Ces impacts de vagues sans air emprisonné sont considérés comme le type d'impact le plus extrême dans la littérature (e.g. Cooker & Peregrine (1992), Hofland et al. (2011)). L'influence de l'inclinaison de l'interface sur la dynamique d'impact et les pressions générées sont analysées dans une configuration de brise-lames réelle. Le modèle d'onde solitaire est utilisé pour générer trois impacts caractéristiques du type flip-through: peu cambré, moyen et très cambré. Le champ de vitesses et la pression à l'intérieur de la fondation sont également étudiés dans cette partie. Les forces horizontales et verticales appliquées sur le caisson sont estimées en intégrant les distributions de pression données par THETIS.La dernière partie de ces travaux montre la stabilité des caissons de brise-lames soumis à des impacts du type flip-through, qui sont ici assimilés à un jet triangulaire (e.g. Cumberbatch (1960), Kihara et al. (2015)). Cette approche simple permet de formuler un modèle semi-analytique pour prédire le mouvement des caissons dû à ce type d'impacts. Après validation avec des simulations numériques, la méthode du jet triangulaire permet d'obtenir des informations sur les forces, la durée du mouvement et le déplacement total en fonction des caractéristiques de la vague et des dimensions du caisson du brise-lames impacté
During the Tohoku tsunami in 2011, field surveys of the east coast of Japan showed the weakness of coastal defences, as even the world largest tsunami breakwater (Kamaishi) almost completely collapsed due to this event. In this PhD, the aim is to investigate the interaction between breakwaters, the most common offshore coastal structures protecting urban areas and harbour entries, and waves and especially tsunami waves.In the first part of the work, the generation of undular bores in the near-shore area of Sendai during the Tohoku event is numerically investigated with the numerical model BOSZ (Boussinesq-type model). It is shown that the second wave, which stroke the coast during this event, transformed into an undular bore, whereas the first wave did not due to steepness differences. Tsunami loads, moments and bearing stress applied on the offshore breakwater of the Soma Port are calculated using two models: BOSZ and THETIS (Navier-Stokes VOF model). BOSZ results are compared to THETIS for the tsunami wave-breakwater interaction. The impact study is carried out at a relatively large scale aiming to have a first estimation of tsunami efforts. Then, a numerical experiment using THETIS is carried out to investigate flip-through impacts on vertical breakwaters. This non-aerated wave impact is considered as the most severe type of impact in the literature (e.g. Cooker & Peregrine (1992), Hofland et al. (2011)) in terms of maximum pressure generated. The influence of the front interface on the impact dynamics and the pressure induced is analysed in a realistic breakwater configuration. Solitary waves are used to obtain three characteristic flip-through impacts involving least steep, medium steep and steepest wave front. The flow field and pressure inside the porous rubble mound are then investigated as well as horizontal and uplift forces applied on the breakwater caisson. The last part of this study is devoted to the stability of breakwater caissons submitted to flip-through impacts. The latter are here assimilated to water wedges (e.g. Cumberbatch (1960), Kihara et al. (2015)). This simple approach allows to formulate a semi-analytical model to predict caisson motion due to this type of impacts. After validation with numerical results, the water wedge method gives rich informations about forces, motion duration and sliding distance depending on the wave impact characteristics and breakwater caisson dimensions

Cataloged from PDF version of thesis.
Includes bibliographical references (p. 105-108).
Sustainable disaster recovery is increasingly understood as a comprehensive process that extends beyond physical reconstruction to include efforts to improve the affected communities' ability to adapt, respond and be more resilient in the face of future emergencies. Additionally, the success of such a complex endeavor requires overseeing agencies to act with speed and efficiency but without compromising the government's safeguards and integrity. Coordinating agencies deployed after emergencies fulfill the efficiency requirement but falter on the other two, while reconstruction through permanent government sometimes lacks speed. I postulate that Implementing Temporary Organizations (ITO) can be a solution. Due to their unique characteristics (experimentation, flexibility, limited duration, smaller size and creation by new regulation), ITOs can be an ideal vehicle for experimentation within the restrictions that regulate government action. They can also be used as laboratories for new governance practices, which once tested and adapted, can be 'absorbed' back by a permanent organization, making more resilient in the future. To explore this hypothesis, this thesis looks at Indonesia's Rehabilitation and Reconstruction Agency (BRR), an ITO in charge of the reconstruction in Aceh and Nias after the devastating tsunami of 2004 and earthquake of 2005 which gained worldwide recognition for its results in rebuilding physical infrastructure. This research looks at how the BRR approached the challenge of training local government officials: instead of traditional capacity-building programs, the BRR's approach to capacity development was the adoption of staff and the creation whole units within the Agency (staffed by locals) which were later 'transplanted' back to the regional government. I find evidence that the BRR's structure as an ITO facilitated experimentation and accelerated its teaching processes in ways not possible for a permanent government or a development agency. Many of the innovations that grew out of this environment were later institutionalized within the local and national government in Indonesia, strengthening them in the long term. These findings demonstrate ITOs are an effective way to manage disaster recovery efforts, and are even helpful in serving as laboratories to produce new knowledge and drive change in permanent organizations.

Understanding the impact of coastal forests on the propagation of rapidly advancing onshore tsunami bores is difficult due to complexity of this phenomenon and the large amount of parameters which must be considered. The research presented in the thesis focuses on understanding the protective effect of the coastal forest on the forces generated by the tsunami and its ability to reduce the propagation and velocity of the incoming tsunami bore. Concern for this method of protecting the coast from tsunamis is based on the effectiveness of the forest and its ability to withstand the impact forces caused by both the bore and the debris carried along by it. The devastation caused by the tsunami has been investigated in recent examples such as the 2011 Tohoku Tsunami in Japan and the Indian Ocean Tsunami which occurred in 2004. This research examines the reduction of the spatial extent of the tsunami bore inundation and runup due to the presence of the coastal forest, and attempts to quantify the impact forces induced by the tsunami bores and debris impact on the structures. This research work was performed using a numerical model based on the Smoothed Particle Hydrodynamics (SPH) method which is a single-phase three-dimensional model. The simulations performed in this study were separated into three sections. The first section focused on the reduction of the extent of the tsunami inundation and the magnitude of the bore velocity by the coastal forest. This section included the analysis of the hydrodynamic forces acting on the individual trees. The second section involved the numerical modeling of some of the physical laboratory experiments performed by researchers at the University of Ottawa, in cooperation with colleagues from the Ocean, Coastal and River Engineering Lab at the National Research Council, Ottawa, in an attempt to validate the movement and impact forces of floating driftwood on a column. The final section modeled the movement and impact of floating debris traveling through a large-scale model of a coastal forest.

Les objectifs de la thèse étaient d’identifier le nombre de MTI en développement, d’évaluer prospectivement l’impact financier que produiront les traitements innovants et de rechercher de nouvelles modalités de paiement des MTI pour aider les décideurs publiques à anticiper l’impact des MTI à court et moyen terme sur le budget de l’assurance maladie. Le nombre de MTI en développement est évalué par le dénombrement des essais cliniques des MTI dans 3 bases de données internationales. Cette étude a montré le grand nombre de MTI en développement et susceptible d’arriver sur le marché. L’impact budgétaire des MTI est évalué. Des modèles de Markov ont été développés pour 3 maladies : Alzheimer, Parkinson et l’insuffisance cardiaque. Ensuite, l’impact des MTI dans 35 maladies sera estimé à l’aide des hypothèses. Cette section montre que les prix élevés des MTI seront inabordables, les payeurs ne pourront pas payer le prix de tous les MTI à l’avance. Une identification des modèles de paiement des thérapies innovantes est effectuée via une revue de la littérature. Ces modèles ont été évalués et discutés durant une réunion d’experts puis un modèle de paiement optimal pour les MTI est suggéré. Des recommandations stratégiques sont présentées pour aider les industriels et les décideurs publiques à assurer l’accès des patients aux thérapies innovantes tout en maintenant la pérennité de l’assurance maladie et évitant la faillite
The objectives of this thesis were to identify the magnitude of the ATMPs pipeline, to assess the budget impact of ATMPs and to suggest new funding models for ATMPs in order to help decision-makers to anticipate the hypothetical short and medium term budget impact of such products. The magnitude of ATMPs pipeline was evaluated by identifying the number and characteristics of ATMPs clinical trials in 3 worldwide clinical trials databases. A large number of ATMPs are in development (939 clinical trials) and may successfully reach the market. Overall, the results showed that the number of ATMPs clinical trials has been consistently growing over the past 15 years. The budget impact of ATMPs was assessed. Markov models were developed to assess the cost-effectiveness and budget impact for ATMPs using 5 efficacy scenarios in Parkinson disease, Alzheimer’s disease and heart failure. Then, an estimation of the budget impact of 35 ATMPs was conducted suggesting that an ATMP can cure all patients. We have shown in this chapter that a cost-effective ATMP may be unaffordable; payers will not be able to pay upfront the costs of all ATMPs. The traditional funding models may not be adaptable for ATMPs. The proposed funding models for innovative high-cost therapies were identified through a literature review, discussed during a consensus meeting and an optimal funding model for ATMPs was recommended.Finally, health policy recommendations for the stakeholders – patients, physicians, payers and manufacturers – are presented. These recommendations aim to help to ensure patient access to innovation while maintaining the sustainability of healthcare system

This paper quantifies and analyzes the economic impact of the Great Tohoku Earthquake and tsunami on the Japanese electricity industry using alternative event study methodology. The data set includes daily stock prices of 11 publicly traded electricity companies. This paper investigates the changes in systematic risk, abnormal returns (ARs), and cumulative abnormal returns (CARs) before and after the natural disaster. In addition, I compare the movement of the stock price in the electricity industry with other indices in Japan to investigate the aggregate level impact on the Japanese economy. By examining the economic impact of the earthquake, this paper provides a visual and a numerical representation of the change in investors’ views on the electricity industry. The results showed no statistically significant changes in ARs in the immediate aftermath of the disaster. On the other hand, statistically significant changes in CARs were found for all 11 electricity companies over an extended period following the disaster. Furthermore, there was a statistically significant increase in systematic risk, especially in the nuclear-committed firms. Although the electricity industry was negatively affected, daily stock prices and CARs show that other industries were not as severely affected. These results provide insight to the global economic and the political implication of the disaster.

Tsunami action had resulted in negative impacts in many ways, it had resulted in great changes to coastal areas, especially in terms of physical change to the coastal landscape, affected on economy, loss of life and physical damage to property. After the devastation, hotel bookings in the island were dropped, people have lost their jobs and some small-scale tourism businesses have got the hardest time as well. Some lifestyle entrepreneurs felt hopeless and have given up on doing business, which resulted to their businesses had to be closed because they were unable to access financial resources and did not have budget to restart their businesses again. Some might take longer time to rehabilitate their firms due to various limitations and conditions. While some have to fight back and develop their firms by turning crisis into opportunity and taking advantage of the crisis. This research is made in order to study and examine the impacts of and the recovery to the 2004 December tsunami disaster in Phuket, especially to small tourism businesses in Karon beach, which will be described through a disaster management model. The goal of this research is to study how the tsunami has affected on small firms and how they performed in order to rehabilitate their businesses, and even how they have been working and cooperating with the local government to draw back tourists to the destination.

The main objective of this study was to investigate and quantify the impact of extreme hydrodynamic forces, similar to those generated by tsunami-induced inundation, on structural elements. As part of a comprehensive experimental program and analytical study, pressures, base shear forces, and base overturning moments generated by hydraulic bores on structural models of various shapes were studied. In addition, the impact force induced by waterborne wooden debris of different shapes and masses on the structural models was also investigated. Two structural models, one with circular and the other with square cross-section, were installed individually downstream of a dam-break wave in a high-discharge flume. Three impounding water heights (550, 850 and 1150 mm) were used to produce dam-break waves, which have been shown to be analogous to tsunami-induced coastal inundation in the form of highly turbulent hydraulic bores. Time-history responses of the structural models were recorded, including: pressures, base shear forces, base overturning moments, lateral displacements, and accelerations. In addition, the flow depth-time histories were recorded at various locations along the length of the flume. Regular and high-speed video cameras were used to monitor the bore-structure interaction. The effect of initial flume bed condition (“wet” or “dry” bed) on the forces and pressures exerted on the structural models were also investigated. Moreover, the vertical distribution of pressure around the models was captured. Simple low-height walls with various geometries were installed upstream from the structural models to investigate their efficiency as tsunami mitigation measures. The experimentally recorded data were compared with those estimated from currently available formulations. The results and analysis of the simulated tsunami-induced bore presented in this study will be of significant use to better estimate forces exerted on structures by tsunami-induced turbulent bores. It is expected that this work will contribute to the new ASCE7 Chapter 6 - Tsunami Loads and Effects in which two of this author’s academic supervisors, Drs. Ioan Nistor and Dan Palermo, are members.

The extensive death toll and sever economical damages brought by the 2004 Indian Ocean tsunami has emphasized the urgent need for assessing the hazard of tsunami in this ocean, and determining the most vulnerable coastlines to the impact of possible tsunami. In this paper the hazard of tsunami for southern coasts of Iran bordering the Indian Ocean is discussed. At first, historical data of tsunami occurrences on the Iranian southern coasts are collected, described and analyzed. Then, numerical simulation of potential tsunamis in the Makran subduction zone is performed and the tsunami wave height distribution along the Iranian coast is calculated. The Makran subduction zone is among two main tsunamigenic zones in the Indian Ocean. In this zone the Oman oceanic plate subducts beneath the Iranian Micro-plate at an estimated rate of about 19 mm/yr. Historically, there is the potential for tsunami generation in this region and several tsunamis attacked the Makran coastlines in the past. The most recent tsunami in this region has occurred on 28 November 1945 which took the lives of more than 4000 people in the coasts of Iran, Pakistan, India, and Oman. Here we examine the seafloor uplift of the Makran zone and its potential for generating destructive tsunamis in the southern coastlines of Iran. Several earthquake scenarios with moment magnitudes ranging between 6.5 and 8.5 are used as initial conditions for analysis. For scenario of an earthquake with magnitude of 8.0, propagation of tsunami waves on coastlines and wave time histories in selected reference locations are calculated.

Presented is an initial discussion on dynamic simulation of tsunami air bag deployment in connection with a number of smart inflatable and deployable structures, called tsunami air bags (TAB) that can be rather quickly set up and strongly anchored to the ocean floor to withstand the impact of a tsunami wave and thus protect the buildings and structures on shore. These dedicated inflatable smart structures are designed such that upon tsunami impact they can perform two smart deployment tasks. The first one is for the structure to deploy in the form of a porous structure containing internal folds and pockets and reconfigure due to tsunami impact to perform energy absorption by forcing the tsunami waves to pass through the porous inflatable structure forcing the tsunami waves to lose kinetic energy due to viscous drag and pressurizing the TABs. The second task is related to a special de sign of the inflatable structure that causes it to deploy to either further vertically rise or become a hollow inflatable dam upon the tsunami impact. In these endeavors a wave generation channel was designed and constructed to perform experiments and to simulate tsunami wave impacts on inflatable structures deploying from an underwater location. The initial observation indicates that TABs have a great potential to mitigate tsunami impacts.

Successive safety improvements for nuclear power plants (NPPs) have been required by society as well as by regulatory agencies because of the nuclear accident at the Fukushima Daiichi Nuclear Power Plant due to the Great East Japan Earthquake and Tsunami. The establishment of a methodology for the fragility evaluation of seawalls is essential for developing a probabilistic risk assessment (PRA) for tsunamis that is applicable to NPPs where the hazard level of tsunamis is high. In the present study, fragility evaluation methods of reinforced concrete (RC) seawalls are documented. Two main damage modes of the seawall, namely overflow and physical damage caused by tsunami wave pressure, were the primary focus. Using the documented fragility evaluation methodology, a conceptual study for evaluating the fragility of a RC seawall against overflow and the impact of tsunami wave pressure is performed, and fragility curves are obtained by considering the following uncertainties: evaluation accuracy of the inundation level and tsunami wave pressure, density of the seawater, compressive strength of concrete, yield strength of reinforcement, and evaluation accuracy of the shear capacity.

The Tohoku Tsunami of March 11, 2011 caused tremendous damage to many coastal buildings, bridges and port facilities. During field surveys following this event, the authors documented a number of structures that were damaged to a near-collapse condition as a result of hydrodynamic loading. Analysis of survivor videos provided information on the tsunami flow characteristics at these locations, allowing for an assessment of current hydrodynamic loading expressions under full-scale conditions. Based on laboratory experiments performed at Oregon State University, the lead author and colleagues developed a new hydrodynamic loading expression for a broken bore striking a vertical wall [1]. This expression was applied to a case study of a large vertical reinforced concrete (RC) wall damaged by an incoming bore strike during the Tohoku Tsunami. The damaged wall is on the seaward side of a high-bay building in the Minami Gamou Sewage Treatment plant near the Sendai coastline. A non-linear finite element model of the building was subjected to the hydrodynamic pressure distribution derived from the laboratory experiments. It is shown by structural analysis of the wall that using this loading expression generates the same yielding response in the wall as observed in the field, as reflected in the deflected shape measured by LiDAR. Similar analysis using current Japan Tsunami design provisions indicates that these provisions are considerably more conservative from a structural perspective than is necessary to resist hydrodynamic loading from a tsunami bore. This paper presents the application of hydrodynamic loading by the leading edge of a bore, determined based on laboratory experiments, to the non-linear analysis of a reinforced concrete building damaged during the Tohoku Tsunami.

Abstract When a large-scale tsunami occurs, structures in the coastal area will be destroyed by the impact of tsunami drifts. In the design of tsunami evacuation facilities and petroleum complexes, it is necessary to estimate the impact force of tsunami drift, which varies in size, shape and mass. Although some design equations have been proposed to estimate the impact force of tsunami drift, the impact force varies depending on various conditions such as the draft of the tsunami drifts, the attitude of the collision, the condition of the surrounding flow field, and the rigidity of the structure, etc. No reasonable design equation has been developed yet to meet all these conditions. Therefore, it is necessary to estimate the impact force of tsunami drift by water tank experiments and numerical simulations. In order to simulate the impact of a tsunami drift on a structure by numerical simulation, it is necessary to solve the coupling of fluid, floating object and structure. In this study, we have developed a simulation system that can simulate the impact force of a tsunami drift with the MPS method, which is a kind of particle method. This simulation system introduces an explicit method for pressure calculation, which allows for relatively large scale numerical calculations. In addition, the system is able to reproduce the deformation of structures as an elastic body due to the impact of tsunami drift. In particular, we have introduced an analytical method that allows us to set the computational time step that satisfy the CFL conditions for elastic and fluid particles, respectively, for stable simulation even when there is a large difference between the velocity of fluid particles and the velocity of structural particles caused by elastic waves. As a result of the comparison of the impact force on the cantilevered beam of the tsunami drift with the simulation and the water tank test, the deformation of the structure at the time of impact was reproduced with more than 90% accuracy.

Due to its position between various tectonic plates, Japan is at constant risk of natural disasters such as volcanic eruptions, earthquakes, and tsunamis. The latter have a great and destructive impact since a large part of the Japanese population lives on coastal plains. The importance of having early warning systems has led Japanese scientists to give particular importance to the study of the seabed and its tectonic characteristics, in order to better understand its geological composition, and to be able to create better and faster early warning systems with new technologies for transmission and data collection.

Southwest British Columbia has some of the highest seismic hazard in Canada and is home to facilities owned by the Department of National Defence which support operations on the west coast of Canada. The potential impact of seismic hazards on these government facilities are investigated here. The hazard is from three primary sources: subduction interface, crustal and in-slab earthquakes. NRCan, in consultation with DRDC have produced representative earthquake scenarios for each of these sources. The subduction scenario we constructed was an M8.9 earthquake extending along the entire Cascadia Subduction Zone from 4 to 18 km depth. We used an M6.8 earthquake occurring along a 30 km fault at between 52 and 60 km depth below Boundary Bay to represent in-slab events. The final scenario, representing a crustal source, was an M6.4 along the central 47 km of the Leech River Valley-Devil's Mountain Fault system. We found that the Cascadia subduction scenario dominated the shaking hazard over much of the study region. Meanwhile, the in-slab and crustal scenarios have higher but more localized hazards in Vancouver and Victoria. In addition to the primary ground motion hazard, we also examined secondary seismic hazards: secondary amplification effects, landslides, liquefaction, surface ruptures, tsunami, flooding, fire, and aftershocks. Each of the secondary hazards had varying impacts depending on the scenario and locations within the region.

On 15 January 2022, the Hunga-Tonga-Hunga-Ha'apai volcano eruption was felt across the Pacific Ocean and beyond, releasing energy equivalent to hundreds of Hiroshima nuclear explosions and creating supersonic air pressure waves that were observed from space. In the archipelago Kingdom of Tonga, the ashfall, tsunami and shock waves caused widespread devastation on several islands. The only fibre-optic cable that connects the islands with the rest of the world was severely damaged, leaving the entire country offline for more than three weeks. The case the Hunga Tonga-Hunga Ha’apai volcano eruption showed that the inability to “be online” becomes a vulnerability in the context of extreme events. This technical background report for the 2021/2022 edition of the Interconnected Disaster Risks report analyses the root causes, drivers, impacts and potential solutions for the Tonga volcano eruption through a forensic analysis of academic literature, media articles and expert interviews.

This study focuses on disaster impacts and recovery in Tamil Nadu, drawing on insights from Chennai city and Nagapattinam district. The research is part of a larger three-year project called “Recovery with Dignity”, which examines the experiences of recovery in post-disaster situations across three states in India – Odisha, Tamil Nadu, and Kerala – and explores how recovery processes represent vulnerable populations. In this report, we focus on three key disasters in Tamil Nadu: the 2004 Indian Ocean Tsunami, the 2015 South India flood, and the 2018 Cyclone Gaja. Through these events, we examine how the ways disasters and their losses are represented shape recovery outcomes. The study uses a range of data, from a review of state policies in Tamil Nadu (2005-2019), an analysis of media articles published in English and Tamil (2004-2019), to interviews with disaster-affected people and secondary stakeholders. The findings indicate that disaster responses and outcomes are highly differentiated based on how disaster-affected people and their needs and losses are represented. To enable inclusive recovery, it is necessary to recognising the heterogenous nature of disaster impacts and acknowledge different ideas of what recovery means.

Natural hazard threats occur in areas of the built environment where buildings, people, and related financial assets are exposed to the physical effects of earth system processes that have a potential to cause damage, injuries, losses, and related socioeconomic disruption. As cities, towns, and villages continue to expand and densify in response to the pressures of urban growth and development, so too do the levels of exposure and susceptibility to natural hazard threat. While our understanding of natural hazard processes has increased significantly over the last few decades, the ability to assess both overall levels of physical exposure and the expected impacts and consequences of future disaster events (i.e., risk) is often limited by access to an equally comprehensive understanding of the built environment and detailed descriptions of who and what are situated in harm's way. This study addresses the current gaps in our understanding of physical exposure to natural hazards by presenting results of a national model that documents characteristics of the built environment for all settled areas in Canada. The model (CanEM) includes a characterization of broad land use patterns that describe the form and function of cities, towns, and villages of varying size and complexity, and the corresponding portfolios of people, buildings and related financial assets that make up the internal structure and composition of these communities at the census dissemination area level. Outputs of the CanEM model are used to carry out a preliminary assessment of exposure and susceptibility to significant natural hazard threats in Canada including earthquake ground shaking; inundation of low-lying areas by floods and tsunami; severe winds associated with hurricanes and tornados; wildland urban interface fire (wildfire); and landslides of various types. Results of our assessment provide important new insights on patterns of development and defining characteristics of the built environment for major metropolitan centres, rural and remote communities in different physiographic regions of Canada, and the effects of ongoing urbanization on escalating disaster risk trends at the community level. Profiles of physical exposure and hazard susceptibility described in this report are accompanied by open-source datasets that can be used to inform local and/or regional assessments of disaster risk, community planning and emergency management activities for all areas in Canada. Study outputs contribute to broader policy goals and objectives of the International Sustainable Development Goals (SDG 2015-2030; Un General Assembly, 2015) and the Sendai Framework for Disaster Risk Reduction (SFDRR 2015-2030; United Nations Office for Disaster Reduction [UNDRR], 2015), of which Canada is a contributing member. These include a more complete understanding of natural hazard risk at all levels of government, and the translation of this knowledge into actionable strategies that are effective in reducing intrinsic vulnerabilities of the built environment and in strengthening the capacity of communities to withstand and recover from future disaster events.

Introduction u cours des deux derniers millénaires, il y a eu plusieurs façons de conserver, transmettre et même créer la connaissance ; la tradition orale, l’écrit manuscrit, l’écrit imprimé et l’écrit numérisé. La tradition orale et le manuscrit ont dominé pendant plus de 1400 ans, et ce, jusqu’à l’apparition du livre imprimé en 1451, résultant de l’invention mécanique de Gutenberg. Il faudra attendre un peu plus de 550 ans, avant que l’invention du support électronique déloge à son tour le livre imprimé, prenant une ampleur sans précédent grâce à la révolution numérique contemporaine, résultat du maillage des technologies de l’informatique, de la robotique et de la science des données. Les premières universités qui sont nées en Occident, au Moyen Âge, ont développé cette tradition orale de la connaissance tout en multipliant l’usage du manuscrit créant ainsi de véritables communautés de maîtres et d’étudiants ; la venue de l’imprimerie permettra la multiplication des universités où l’oral et l’écrit continueront de jouer un rôle déterminant dans la création et la transmission des connaissances même si le « support » a évolué du manuscrit à l’imprimé puis vers le numérique. Au cours de toutes ces années, le modèle de l’université s’est raffiné et perfectionné sur une trajectoire somme toute assez linéaire en élargissant son rôle dans l’éducation à celui-ci de la recherche et de l’innovation, en multipliant les disciplines offertes et les clientèles desservies. L’université de chaque ville universitaire est devenue une institution florissante et indispensable à son rayonnement international, à un point tel que l’on mesure souvent sa contribution par la taille de sa clientèle étudiante, l’empreinte de ses campus, la grandeur de ses bibliothèques spécialisées ; c’est toutefois la renommée de ses chercheurs qui consacre la réputation de chaque université au cours de cette longue trajectoire pendant laquelle a pu s’établir la liberté universitaire. « Les libertés universitaires empruntèrent beaucoup aux libertés ecclésiastiques » : Étudiants et maîtres, qu'ils furent, ou non, hommes d'Église, furent assimilés à des clercs relevant de la seule justice ecclésiastique, réputée plus équitable. Mais ils échappèrent aussi largement à la justice ecclésiastique locale, n'étant justiciables que devant leur propre institution les professeurs et le recteur, chef élu de l’université - ou devant le pape ou ses délégués. Les libertés académiques marquèrent donc l’émergence d'un droit propre, qui ménageait aux maîtres et aux étudiants une place à part dans la société. Ce droit était le même, à travers l'Occident, pour tous ceux qui appartenaient à ces institutions supranationales que furent, par essence, les premières universités. À la fin du Moyen Âge, l'affirmation des États nationaux obligea les libertés académiques à s'inscrire dans ce nouveau cadre politique, comme de simples pratiques dérogatoires au droit commun et toujours sujettes à révision. Vestige vénérable de l’antique indépendance et privilège octroyé par le prince, elles eurent donc désormais un statut ambigu » . La révolution numérique viendra fragiliser ce statut. En effet, la révolution numérique vient bouleverser cette longue trajectoire linéaire de l’université en lui enlevant son quasi monopole dans la conservation et le partage du savoir parce qu’elle rend plus facile et somme toute, moins coûteux l’accès à l’information, au savoir et aux données. Le numérique est révolutionnaire comme l’était l’imprimé et son influence sur l’université, sera tout aussi considérable, car cette révolution impacte radicalement tous les secteurs de l’économie en accélérant la robotisation et la numérisation des processus de création, de fabrication et de distribution des biens et des services. Ces innovations utilisent la radio-identification (RFID) qui permet de mémoriser et de récupérer à distance des données sur les objets et l’Internet des objets qui permet aux objets d’être reliés automatiquement à des réseaux de communications .Ces innovations s’entrecroisent aux technologies de la réalité virtuelle, à celles des algorithmiques intelligentes et de l’intelligence artificielle et viennent littéralement inonder de données les institutions et les organisations qui doivent alors les analyser, les gérer et les protéger. Le monde numérique est né et avec lui, a surgi toute une série de compétences radicalement nouvelles que les étudiants, les enseignants et les chercheurs de nos universités doivent rapidement maîtriser pour évoluer dans ce Nouveau Monde, y travailler et contribuer à la rendre plus humain et plus équitable. En effet, tous les secteurs de l’activité commerciale, économique, culturelle ou sociale exigent déjà clairement des connaissances et des compétences numériques et technologiques de tous les participants au marché du travail. Dans cette nouvelle logique industrielle du monde numérique, les gagnants sont déjà bien identifiés. Ce sont les fameux GAFAM (Google, Apple, Facebook, Amazon et Microsoft) suivis de près par les NATU (Netflix, Airbnb, Tesla et Uber) et par les géants chinois du numérique, les BATX (Baidu, Alibaba, Tenant et Xiaomi). Ces géants sont alimentés par les recherches, les innovations et les applications mobiles (APPs) créées par les partenaires de leurs écosystèmes regroupant, sur différents campus d’entreprises, plusieurs des cerveaux qui sont au cœur de cette révolution numérique. L’université voit donc remise en question sa capacité traditionnelle d’attirer, de retenir et de promouvoir les artisans du monde de demain. Son aptitude à former des esprits critiques et à contribuer à la transmission des valeurs universelles est également ébranlée par ce tsunami de changements. Il faut cependant reconnaître que les facultés de médecine, d’ingénierie et de sciences naturelles aux États-Unis qui ont développé des contacts étroits, abondants et suivis avec les hôpitaux, les grandes entreprises et l’administration publique et cela dès la fin du 19e siècle ont été plus en mesure que bien d’autres, de recruter et retenir les gens de talent. Elle ont énormément contribué à faire avancer les connaissances scientifiques et la scolarisation en sciences appliquées ..La concentration inouïe des Prix Nobel scientifiques aux États-Unis est à cet égard très convaincante . La révolution numérique contemporaine survient également au moment même où de grands bouleversements frappent la planète : l’urgence climatique, le vieillissement des populations, la « déglobalisation », les déplacements des populations, les guerres, les pandémies, la crise des inégalités, de l’éthique et des démocraties. Ces bouleversements interpellent les universitaires et c’est pourquoi leur communauté doit adopter une raison d’être et ainsi renouveler leur mission afin des mieux répondre à ces enjeux de la civilisation. Cette communauté doit non seulement se doter d’une vision et des modes de fonctionnement adaptés aux nouvelles réalités liées aux technologies numériques, mais elle doit aussi tenir compte de ces grands bouleversements. Tout ceci l’oblige à s’intégrer à des écosystèmes où les connaissances sont partagées et où de nouvelles compétences doivent être rapidement acquises. Le but de ce texte est de mieux cerner l’ampleur du défi que pose le monde numérique au milieu universitaire et de proposer quelques idées pouvant alimenter la réflexion des universitaires dans cette démarche d’adaptation au monde numérique. Or, ma conviction la plus profonde c’est que la révolution numérique aura des impacts sur nos sociétés et notre civilisation aussi grands que ceux provoqués par la découverte de l’imprimerie et son industrialisation au 15e siècle. C’est pourquoi la première section de ce document est consacrée à un rappel historique de la révolution de l’imprimerie par Gutenberg alors que la deuxième section illustrera comment les caractéristiques de la révolution numérique viennent soutenir cette conviction si profonde. Une troisième section fournira plus de détails sur le défi d’adaptation que le monde numérique pose aux universités alors que la quatrième section évoquera les contours du changement de paradigme que cette adaptation va imposer. La cinquième section servira à illustrer un scénario de rêves qui permettra de mieux illustrer l’ampleur de la gestion du changement qui guette les universitaires. La conclusion permettra de revenir sur quelques concepts et principes clefs pour guider la démarche vers l’action. L’université ne peut plus « être en haut et seule », elle doit être « au centre et avec » des écosystèmes de partenariats multiples, dans un modèle hybride physique/virtuel. C’est ainsi qu’elle pourra conserver son leadership historique de vigie du savoir et des connaissances d’un monde complexe, continuer d’établir l’authenticité des faits et imposer la nécessaire rigueur de la science et de l’objectivité.
