Abstract (sommario):

In order to study seismic behavior of half-speed turbine-generator foundation under horizontal earthquake loading in different directions, the 1/10 scaled model was designed and fabricated. The rigid foundation of half-speed turbine-generator sets can be seen as a complex space frame system. The tests were conducted under eight earthquake waves in two directions separately. The loading directions were along the axis of longitudinal and transverse. The seismic response of displacement and story drift was investigated by a pseudodynamic test. The hysteresis behavior and crack propagation were analyzed. From the research, it is shown that the maximum displacement of the foundation under the earthquake of intensity 7 is 15.20 mm (longitudinal), basically in the range of elastic deformation. The seismic response of earthquake input in different directions is obviously different. Under the same earthquake input, the seismic displacement along the axis of longitudinal is larger than that of transverse. Under the rarely earthquake of intensity 8, the foundation still keeps good working condition. The maximum elastic-plastic story drift is 1/191 under the limit value 1/50 provided in the Code for Seismic Design of Buildings. The deformation capacity of the structure meets the requirements of the current seismic design code of China.

Abstract (sommario):

Earthquakes are events that come suddenly. Until now, the occurrence of the earthquake has not yet been predicted. Likewise, the risk posed by earthquakes cannot be predicted, but can be reduced through disaster mitigation. However, mitigation has not been able to solve problems that occur after the earthquake, such as constraints on meeting electrical energy. Indonesia has the potential to utilize earthquake vibrations into electricity, through the Earthquake Power Plant (PLTGB) proposed by the author. One of the techniques that can be used for the process of converting earthquake vibration energy into electrical energy is using piezoelectric materials. Piezoelectric material is a material that has high advantages with a stable energy density and does not require an external power so that its utilization produces large profits. The process of harvesting electrical energy is obtained from applying pressure to the piezoelectric material at a certain frequency, so that the piezoelectric material can function as an electric generator. The type of writing used in this paper is literature review, with secondary data sources obtained from various literatures. Data collection techniques using documentation study. Data analysis used an interactive analysis model, namely data collection, data reduction, data presentation and drawing conclusions. The principle of PLTGB application is carried out in two periods, namely the period during the earthquake and the period outside the earthquake with the aim of storing energy reserves outside the earthquake. The PLTGB construction material is implanted under the highway at 5 meters near the zebra crossing which will be made like a bump, so that during the earthquake period the material will work as in principle. However, outside the earthquake period, when the vehicle stops or runs, it will put mechanical pressure on the piezoelectric which can generate electric current. The material to be used as a piezoelectric in PLTGB is Barium Titanate (BaTiO3). This material is based on normal ferroelectricity which is strong for transducer induction when compared to the magnitude of its polarization, the amount of permittivity, and the amount of stress induction that this material can reach. The first stage of PLTGB implementation is creating a pilot area, the second stage of evaluation, the third stage of promotion, the fourth stage of PLTGB socialization, and the fifth stage of developing PLTGB nationally. For Indonesia, PLTGB has the potential to be applied. It is hoped that the electrical energy produced by PLTGB can be used for post-earthquake activities.

Abstract. In the paper dynamics of large flexible structures imposed on earthquakes and high amplitude vibrations is regarded. Precise dynamic equations of flexible systems are the basis for reliable motion simulation and analysis of loading of the design scheme elements. Generalized Newton–Euler dynamic equations for rigid and flexible bodies are applied. The basement compulsory motion realized because of earthquake or wave propagation is presented in the dynamic equations as reonomic constraints. The dynamic equations, algebraic equations and reonomic constraints compile a system of differential algebraic equations which are transformed to a system of ordinary differential equations with respect to the generalized coordinates and the reactions due to the reonomic constraints. Examples of large flexible structures and wind power generator dynamic analysis are presented.

Abstract (sommario):

Large turbine–generator foundation can reduce the vibration in an effective way by mounting vibration isolating springs when the equipments are operating. But under strong earthquake actions, the research of seismic behavior is presently limited to theoretical calculation and there are no test results or observation data. In this paper, 1:10 spring vibration isolating foundation model is made to carry out a pseudo–dynamic seismic test. This paper also analyzes the deform distribution of column and spring of turbine–generator foundation under horizontal earthquake actions. The test results show that because of the spring of column top, deform distribution of foundation has changed; column top displacement of each column is different; spring can regulate the internal force of the column and these springs are also able to resist horizontal earthquake action when they are reducing the vibration of the equipments.

Abstract (sommario):

September 28th, 2018, Donggala-Palu earthquake M 7.5 occurred at depth of 12 km and generated tsunami to be released off the coast in Palu Bay. The tsunami that occurred in Palu was very interesting because the results of the earthquake source mechanism Palu had a type of strike-slip fault that should not have generated a tsunami. This study purpose to estimate the characteristics of the Donggala-Palu tsunami based on rupture duration ( and orientation fault activated using the HC-plot method. The data used in this study are data waveforms from 17 seismic stations and CMT Global catalog data with the area of research 0.87 0 N-1.78 0S dan 118.640E- 120.95 0E. The waveform data used is a phase P-PP vertical component signal with a Bandpass-filter 1-5 Hz for determination . The fastest rupture duration from the earthquake source is obtained from the calculation of each station. Delay time measurement after P wave for 90% (T0.9), 80% (T0.8), 50% (T0.5), dan 20% (T0.2) from its peak value. Then the HC-plot method is used to estimate the orientation of generator fault Palu earthquake and the direction of rupture from the focal mechanism. From the results of processing obtained 2 pairs of seismic stations with almost the same distance but with different azimuths. The fastest rupture duration is at BBSI station with value of 82.014 s and distance from station to epicenter . So that the rupture direction is in the azimuth from the north. The result of fault orientation was obtained hypocenter distance to the centroid for nodal plane 1 is 6.32 km and nodal plane 2 is 30.17 km with distance centroid to hypocenter is 31.22 km. So in Palu earthquake, the tsunami generator fault was in nodal plane 1 with direction north-south. Criteria obtained indicate that the Palu earthquake M 7.5 has potential for a tsunami because of its value has meet ≥ 65 s, but from the result of the focal mechanism direction field not passing through the Palu bay is thought to be another parameter that generates a tsunami and Palu koro fault line uncharted.

Abstract (sommario):

In the recent years, the wind energy building is rapidly developed world wide as a new kind of building style, for its low price and it’s friendly to environment. The wind energy building a combination of wind power and buildings, it could turn wind power into electric energy, which also could relieve the energy scarcity problem to some extent. The wind driven generator and high-rise building structure were integrated, and ANSYS was used to complete the analysis of the behaviors of structures with and without wind generator, under EI-Centro earthquake wave and Taft earthquake wave. By comparing the results of those two models, the feasibility of the wind energy and building integration was verified.

Abstract (sommario):

We designed a convolutional neural network application to detect seismic precursors in geomagnetic field records. Earthquakes are among the most destructive natural hazards on Earth, yet their short-term forecasting has not been achieved. Stress loading in dry rocks can generate electric currents that cause short-term changes to the geomagnetic field, yielding theoretically detectable pre-earthquake electromagnetic emissions. We propose a CNN model that scans windows of geomagnetic data streams and self-updates using nearby earthquakes as labels, under strict detectability criteria. We show how this model can be applied in three key seismotectonic settings, where geomagnetic observatories are optimally located in high-seismicity-rate epicentral areas. CNNs require large datasets to be able to accurately label seismic precursors, so we expect the model to improve as more data become available with time. At present, there is no synthetic data generator for this kind of application, so artificial data augmentation is not yet possible. However, this deep learning model serves to illustrate its potential usage in earthquake forecasting in a systematic and unbiased way. Our method can be prospectively applied to any kind of three-component dataset that may be physically connected to seismogenic processes at a given depth.

Abstract (sommario):

Abstract: Past observations during a disaster identify that when children are separated from parents, they suffer due to the inability to comprehend disaster mitigation concepts. This study proposes a process from the existing framework K-Nearest Neighbor (KNN) and Term Frequency - Inverse Document Frequency (TF-IDF) for extracting a large body of knowledge in the form of documents into simple words. Those simple words can be arranged into contextual lyrics utilizing an Artificial Intelligence lyrics generator and then orchestrated into a song using a music generator. The piece, which is the output of the proposed process, is utilized to transfer the knowledge about earthquake disaster mitigation to children. A quantitative analysis of questionnaires on students aged 9-10 in Banda Aceh shows the song's highly significant effect in transferring the knowledge about earthquake disaster mitigation to children.

Abstract (sommario):

La France métropolitaine est éloignée des principales limites de plaques tectoniques. De ce fait, l'origine de la sismicité est plus difficile à comprendre que dans les régions actives localisées le long des limites de plaques. De plus, les données sismiques disponibles (séismes, accumulation des contraintes dans le sol, failles, mécanismes au foyer, etc.) y sont moins nombreuses. Ces observations sont deux des principaux freins rencontrés lorsque l'on souhaite caractériser l'aléa sismique sur un territoire à sismicité faible à modérée. L'approche proposée dans cette thèse s'appuie sur un générateur stochastique produisant des séismes synthétiques en combinant des observations de terrain et des connaissances théoriques sur la sismicité du territoire d'étude. Ce générateur de séismes se divise en trois parties : (i) le tirage temporel des séismes principaux, suivi du (ii) tirage de leur localisation conditionné par la magnitude et enfin de (iii) la production de répliques associées aux séismes principaux. Le tirage temporel est réalisé à l'aide d'une distribution fréquence – magnitude (DFM) calculée sur l'intégralité du territoire d'étude via la méthode non paramétrique des temps de latence. Ce calcul à l'échelle du territoire entier permet d'augmenter le nombre de données, de diminuer les périodes de retour et donc d'estimer les fréquences de chaque magnitude directement à partir des données. Une attention particulière a été portée à la méthode des temps de latence afin de pallier la faible quantité de données observées notamment pour les fortes magnitudes. Le tirage spatial des séismes principaux nécessite, quant à lui, une régionalisation et une densité spatiale caractérisant la sismicité. La régionalisation permet de limiter spatialement la magnitude maximale autorisée des séismes synthétiques. La localisation d'un séisme synthétique d'une magnitude donnée est tirée dans la densité spatiale uniquement au sein des régions autorisant cette magnitude. Les répliques sont ensuite générées autour des séismes principaux à partir de la loi de Bath et de la distribution proportion – magnitude des répliques. L'aléa associé à chaque séisme (principal et réplique) généré est calculé à l'aide de modèles de prédiction des mouvements du sol pondérés. La pondération est dépendante de la magnitude du séisme et de la distance séisme – site. Cette pondération s'effectue en utilisant la base de données européenne d'accélérations du sol RESORCE. Enfin, l'observation en un site donné des aléas produits par les séismes synthétiques sur un million d'années permet d'estimer les probabilités annuelles de dépassement de seuils d'aléa donnés
French mainland seismicity is considered as low to moderate due to its remoteness from tectonic plate boundaries. A first consequence is that the origins of its seismicity are harder to understand than in active regions close to tectonic plate boundaries. Another consequence is the lack of available data (earthquakes recorded but also strain rates, active faults...). These two observation make difficult to estimate seismic hazard in low-to-moderate seismic areas. The proposed approach is to generate synthetic earthquakes by combining observation and theoretical knowledge on the seismicity of the studied territory. This generator is based on a three-step scheme: (i) the temporal draw of main shocks, (ii) their spatial draw conditioned by magnitude and finally (iii) the generation of aftershocks they produce. The temporal step needs a recurrence rate. Past seismicity of the whole studied area is analysed thanks to the non-parametric inter event time method in order to obtain this wished recurrence rate. Computing the recurrence rate at the whole territory scale allows to keep the maximum quantity of data, reduce the return periods and so estimate main shock frequencies directly form observed data for each magnitude. An implementation has been developed to overcome the accuracy fall of the inter event time method observed when data are sparse. The spatial step needs a regionalization and a spatial density representing seismicity. The regionalization allows maximum magnitude limitation in space: each region is characterized by an allowed maximal magnitude. Location of a synthetic earthquake with a given magnitude is drawn in the spatial density only within regions that allow this magnitude. Aftershocks are generated around main shocks thanks to the Bath law and the proportion – magnitude distribution of aftershocks. The seismic hazard produced by each of the generated earthquakes (main shocks and aftershocks) is computed thanks to a set of weighted Ground-Motion Prediction Equations. The weights are obtained as function of magnitude and distance thanks to The European ground-motion database RESORCE. Finally, from direct observation of the seismic hazard produced by synthetic earthquakes over one million years, annual probabilities of exceedance can be calculated with ease

Abstract (sommario):

Quantitative and qualitative assessment of the seismic risk to highway bridges is crucial in pre-earthquake planning, and post-earthquake response of transportation systems. Such assessments provide valuable knowledge about a number of principal effects of earthquakes such as traffic disruption of the overall highway system, impact on the regions' economy and post-earthquake response and recovery, and more recently serve as measures to quantify resilience. Unlike previous work, this study captures unique bridge design attributes specific to California bridge classes along with their evolution over three significant design eras, separated by the historic 1971 San Fernando and 1989 Loma Prieta earthquakes (these events affected changes in bridge seismic design philosophy). This research developed next-generation fragility curves for four multispan concrete bridge classes by synthesizing new knowledge and emerging modeling capabilities, and by closely coordinating new and ongoing national research initiatives with expertise from bridge designers. A multi-phase framework was developed for generating fragility curves, which provides decision makers with essential tools for emergency response, design, planning, policy support, and maximizing investments in bridge retrofit. This framework encompasses generational changes in bridge design and construction details. Parameterized high-fidelity three-dimensional nonlinear analytical models are developed for the portfolios of bridge classes within different design eras. These models incorporate a wide range of geometric and material uncertainties, and their responses are characterized under seismic loadings. Fragility curves were then developed considering the vulnerability of multiple components and thereby help to quantify the performance of highway bridge networks and to study the impact of seismic design principles on the performance within a bridge class. This not only leads to the development of fragility relations that are unique and better suited for bridges in California, but also leads to the creation of better bridge classes and sub-bins that have more consistent performance characteristics than those currently provided by the National Bridge Inventory. Another important feature of this research is associated with the development of damage state definitions and grouping of bridge components in a way that they have similar consequences in terms of repair and traffic implications following a seismic event. These definitions are in alignment with the California Department of Transportation's design and operational experience, thereby enabling better performance assessment, emergency response, and management in the aftermath of a seismic event. The fragility curves developed as a part of this research will be employed in ShakeCast, a web-based post-earthquake situational awareness application that automatically retrieves earthquake shaking data and generates potential damage assessment notifications for emergency managers and responders.

Abstract (sommario):

A number of artificially generated earthquake time-histories (AGETH) fitting to a Eurocode 8 (EC8) response spectrum are randomly generated using SIMQKE software and the average generated spectrum compares well with the EC8 one. Two Finite element (FE) smeared crack models, named Multi-crack and Craft, are well validated against experimental data of concrete and Reinforced concrete (RC) structures under monotonic and cyclic loadings. They are then used in the analysis of RC bridge piers under the AGETH. Several techniques including Fourier analysis, normalised cumulative spectrum, energy dissipation, damage index as well as probability applications are applied to quantify the structural response and damage. Based on the convergence of the representative responses under different numbers of AGETH, a minimum representative number of AGETH from 6 to 11 may be sufficient depending on the confidence band width from the mean of all damage responses. Effects of several parameters of the earthquake and structure to the dynamic response and damage of the bridge pier are investigated. Throughout these parametric studies, several of the common circumstances that structural engineers face are addressed and the proposed number of artificial earthquake time-histories required for non-linear dynamic analysis is thereby validated.

Abstract (sommario):

Following the evolution of a damage avoidance design (DAD) frame system, with rocking beam-column joints, at the University of Canterbury, analytical studies are carried out to evaluate the performance of proposed structures, and verify the proposed design methodology. A probabilistic seismic risk assessment methodology is proposed, from which the expected annualised financial loss (EAL) of a structure can be calculated. EAL provides a consistent basis for comparison of DAD frame systems with state-of-practice ductile monolithic construction. Such comparison illustrates the superior performance of DAD frame systems. The proposed probabilistic seismic assessment methodology requires the response of the structure to be evaluated over a range of seismic intensities. This can be achieved by carrying out an incremental dynamic analysis, explicitly considering seismic randomness and uncertainty; or from a pushover analysis, and assuming an appropriate value of the dispersion. By combining this information with the seismic hazard, probabilistic response curves can be derived, which when combined with information about damage states for the particular structure, can be transformed into 'resilience curves'. Integration of information regarding the financial loss occurring due to each of the damage states, results in an estimate of EAL.

Abstract (sommario):

The Central Andean Plateau (CAP), as defined by elevations in excess of 3 km, extends over 1800 km along the active South American Cordilleran margin making it the second largest active orogenic plateau on Earth. The uplift history of this high Plateau, with an average elevation around 4 km above sea level, remains uncertain as paleoelevation studies along the CAP suggest a complex, nonuniform uplift history. As part of the Central Andean Uplift and the Geodynamics of High Topography (CAUGHT) project, we image the S wave velocity structure of the crust and upper mantle using surface waves measured from ambient noise and teleseismic earthquakes to investigate the upper mantle component of plateau uplift. We observe three main features in our S wave velocity model including (1) a positive velocity perturbation associated with the subducting Nazca slab; (2) a negative velocity perturbation below the sub-Andean crust that we interpret as anisotropic Brazilian cratonic lithosphere; and (3) a high-velocity feature in the mantle above the slab that extends along the length of the Altiplano from the base of the Moho to a depth of similar to 120 km. A strong spatial correlation exists between the lateral extent of this high-velocity feature and the relatively lower elevations of the Altiplano basin suggesting a potential relationship. Determining if this high-velocity feature represents a small lithospheric root or foundering of orogenic lithosphere requires more integration of observations, but either interpretation implies a strong geodynamic connection with the uppermost mantle and the current topography of the northern CAP.

Abstract (sommario):

In the last decades, although the scientific community has attempted to explain a series of complex phenomena, ranging from natural hazards to physical conditions and economic crises, aspects of their generation process still escape our full understanding. The present thesis intends to promote our understanding of the spatiotemporal behavior and the generation mechanisms that govern large and strong earthquakes, employing a broad multidisciplinary perspective for the interpretation of catastrophic events. Two main questions are debated. The first question concentrates on “whether the generation process of an extreme event has more than one facets prior to its final appearance”. In the scientific study of earthquakes, attention is drawn to the predictive capability and monitoring of different precursory observations. Among them preseismic electromagnetic emissions have been also observed indicating that the science of earthquake prediction should be from the start multidisciplinary. Drawing on recently introduced models for earthquake dynamics, that address issues such as long-range correlations, self-affinity, complexity-organization and fractal structures, the present work endeavors to further penetrate on the analysis of preseismic electromagnetic emissions and elucidate their link with the generation process of large and strong earthquakes. A second question deals with “whether there is a unified approach for the study of catastrophic events”. This question implies the possibility for common statistical behavior of diverse extreme events and the potential for transferability of methods from the study of earthquake dynamics across other fields. On these grounds, the present work extends the focus of inquiry to the analysis of electroencephalogram recordings related to epileptic seizures, in the prospect to identify common mechanisms that may explain the nature and the generation process of both phenomena, and to open up different directions for future research. Finally, with a view to consider alternative ways of studying key theoretical principles associated with the generation process of catastrophic phenomena, a relevant framework based on proposed algorithms is presented, focusing on parameters such as: the energy of earthquakes, the mean and maximum magnitude of the sample, the probability that two samples may come from the same population. Such an attempt aims to contribute to the knowledge of natural phenomena, by extending the existing theory and models and providing a few more ways for their interpretation.

Abstract (sommario):

The main purpose of the textbook is to acquaint students and engineers with the principles of design and construction of buildings and structures in seismic areas. The tutorial sets out the basic principles of design and construction of frame, large-panel buildings, buildings with load-bearing walls made of small-piece stones and large blocks, buildings made of local materials, frameless buildings made of monolithic reinforced concrete.

Abstract (sommario):

AbstractThis paper introduces three catastrophic landslide disasters on the tectonic orogenic belt in Western Japan caused by rainfalls or earthquakes and the countermeasures against them. The first case story is the mega slide of Unzen-Mayuyama of Quaternary volcanic rock due to the 1792 earthquake. The landslide and subsequent tsunami caused the worst Japanese landslide-induced disaster in Shimabara and Ariake Bay. The stone pillars installed after the disaster, indicating the arrival points of the tsunami will generate awareness of the tsunami caused by landslides for future generations. Secondly, the Kumamoto earthquake of 2016 has induced many shallow landslides on tephra-covered slopes and massive slope failures that disrupted highway and rail traffic. Unmanned construction to secure workers has been introduced to stabilize the slope failure early. There is an urgent need for research on the identification of hazardous slopes for landslides on tephra-covered slopes. Thirdly, the Hiroshima disaster in 2018 was characterized by landslides, mainly in the suburban residential areas in Hiroshima City, where heavy rains have caused landslides from the weathered soil, so-called “Masa,” of granitic rocks. Similar disasters occurred in 1999 and 2014 in Hiroshima. The restoration project has been carried out by adopting necessary structural measures such as Sabo dams and non-structural measures such as land use regulations and/or early warning systems based on the Sediment Disaster Prevention Act.

Abstract (sommario):

A monitoring system intended to track vibrations associated with the electric generation of an emergency diesel generator (EDG) at a nuclear power plant was originally installed to trip generators during potential out-of-balance shaking. Years after original installation, plant engineers raised questions as to whether the monitoring system would have functioned properly in the event of excessive vibrations associated with earthquake ground shaking. As part of the plant’s examination of this issue, analytical models were developed for three vibration transducers via experimental characterization. A suite of ground motion records were selected and scaled such that their mean and dispersion was representative of the design basis event (DBE) level of intensity at the plant site. The scaled suite of ground motions was used as an input for a three-dimensional analytical model representing the structure and soil-foundation interface where the EDGs were installed. The voltage signal from the analytical transducer model provided input to the physical vibration alarm monitor. This monitor filters the vibration transducer signal and generates an output to a time delay relay that will trip the EDG if the output from the vibration monitor is not reset within five seconds. The analysis and testing completed and described in this paper concluded that a DBE would not have caused the vibration monitoring circuit to spuriously trip the EDGs.

Abstract (sommario):

After observations of many seismic disasters, let is found that many structures were just damaged slightly or even without any damage such as hospitals, high technology factories, computer generator rooms, but huge damage to internal installations was caused by earthquakes. Therefore, in addition to promoting the earthquake-resistant capacity of a structure, it is also important to ensure the safety of ancient objects and instruments in the structure. Structural control has been recognized as an effective and attractive method for preventing structural damage from earthquakes. In this study, shaking table tests of the high-end server equipment equipped with the multiple friction pendulum system (MFPS) were carried out to study the earthquake-proof benefit of the MFPS isolator. The MFPS isolator can not only shift the natural periods of high-end server equipments away from the rich period contents of earthquake motions, but also provide considerable hysteretic friction damping to absorb the input energy of earthquakes to insure the sensitive equipments unharmed during earthquakes.

Abstract (sommario):

Today, clean or renewable energy is highly demanded for realization of the sustainable earth. The most promising methods among renewable energies are wind power, solar, water power, and biomass energies. They need to apply generators except for a solar energy case. The first study for development of generators was product dissection of eight different generators, which resulted that there seem no rule for the most suitable design approach. They include 4 wind power, two water, and 2 vehicle generators. In such dissected 8 generators there are all different coil number, magnet number, way of coil winding, phase for coil connection, and etc. Starting the study of disk-shape rotor with magnets in the outer periphery, the capability of power generator was studied, and it resulted that it is not sufficient. As a second step, an axial gap type generator was investigated using rare-earth permanent magnets and core-less coils for both face sides for coil assembly. The first objective of this research is to establish an effective wind power generator, which should be useful even under a weak wind condition like at a ground level. The idea of core-less coil (without pulling against each other between coils and magnets) is to obtain easy rotation in the area where is not so strong wind blow condition. The second objective of this research is to establish a hybrid wind and solar power energy system. The system is considered to be used in the case of disaster event such as an earthquake occurrence. Because big earthquakes are expected in the coming 30–40 years with the probability of 40–50% in the south part of Japan, the self-powered lights need in such a disaster occurrence case. Although wind power generators are effective at mountainous areas, we think we need to consider to apply a wind power generator in populated areas. Combining a wind power generator with a solar cell, a self-powered street light can be utilized. In the following, the design and development of generator and a possibility of the hybrid system by wind power and solar cell are reported.

Abstract (sommario):

In the present study deterministic earthquake scenarios for the city of Varna - the thirdlargest city in Bulgaria are presented. By deterministic scenario, it is mean a representation of the severity of ground shaking over an urban area, using one or more hazard descriptors. The assessment of seismic hazard and generation of earthquake scenarios is the first step of seismic risk evaluation and society prevention. Seismic history of Varna shows that the hazard for the city is mainly influence by the earthquakes occurred in the seismogenic zone Shabla (Kaliakra fault system). The local ground shaking levels are computed using the six ground motion prediction equations (GMPE�s) for tectonically active regions that are previously selected. A reliable geotechnical zonation of the city of Varna was incorporated in the earthquake scenario generation. Deterministic ground shaking scenarios for the city of Varna are generated for two scenario earthquakes with different location and magnitudes are considered. The generated scenarios are described in terms of MSK (=EMS98) intensity, peak ground acceleration and velocity and in spectral accelerations for Sa (0.3s) and Sa (1.0s). The results in PGA and MSK intensity for scenario MW7.2 quake located on strike slip Kaliakra fault are mapped. The estimated peak ground accelerations for MW7.2 quake vary between 0.07 and 0.14 g.

Abstract (sommario):

This study estimates the effects of the 1970 Ancash earthquake on human capital accumulation on the affected and subsequent generation, 37 years after the shock, using the Peruvian censuses of 1993 and 2007. The main finding is that males affected by the earthquake in utero completed on average 0. 5 years less schooling while females affected by the earthquake completed 0. 8 years less schooling. Surprisingly, those whose mothers were affected at birth by the earthquake have 0. 4 less years of education, while those whose fathers were affected by the earthquake at birth have no effects on their education. The evaluation of other outcomes also suggests that the level of welfare of the affected individuals has been negatively impacted in the long run. The present investigation supports previous literature on shocks in early childhood, providing evidence of the existence of intergenerational transmission of shocks.

Abstract (sommario):

A set of global and region-specific ground-motion models (GMMs) for subduction zone earthquakes is developed based on the database compiled by the Pacific Earthquake Engineering Research Center (PEER) Next Generation Attenuation - Subduction (NGA-SUB) project. The subset of the NGA-SUB database used to develop the GMMs includes 3914 recordings from 113 subduction interface earthquakes with magnitudes varying between 5 and 9.2 and 4850 recordings from 89 intraslab events with magnitudes varying between 5 and 7.8. Recordings in the back-arc region are excluded, except for the Cascadia region. The functional form of the model accommodates the differences in the magnitude, distance, and depth scaling for interface and intraslab earthquakes. The magnitude scaling and geometrical spreading terms of the global model are used for all regions, with the exception of the Taiwan region which has a region-specific geometrical spreading scaling. Region-specific terms are included for the large distance (linear R) scaling, VS30 scaling, Z2.5 scaling, and the constant term. The nonlinear site amplification factors used in Abrahamson et al. (2016) subduction GMM are adopted. The between-event standard deviation piece of the aleatory variability model is region and distance independent; whereas, the within-event standard deviations are both region and distance dependent. Region-specific GMMs are developed for seven regions: Alaska, Cascadia, Central America, Japan, New Zealand, South America, and Taiwan. These region-specific GMMs are judged to be applicable to sites in the fore-arc region at distances up to 500 km, magnitudes of 5.0 to 9.5, and periods from 0 to 10 sec. For the Cascadia region, the region-specific model is applicable to distances of 800 km including the back-arc region. For the sites that are not in one of the seven regions, the global GMM combined with the epistemic uncertainty computed from the range of the regional GMMs should be used.

Abstract (sommario):

While modern overpass bridges are safe against collapse, their functionality will likely be compromised in case of design-level or beyond design-level earthquake, which may generate excessive residual displacements of the bridge deck. Presently, there is no validated, quantitative approach for estimating the operational level of the bridge after an earthquake due to the difficulty of accurately simulating residual displacements. This research develops a novel method for probabilistic evaluation of the post-earthquake functionality state of the bridge; the approach is founded on an explicit evaluation of bridge residual displacements and associated traffic capacity by considering realistic traffic load scenarios. This research proposes a high-fidelity finite-element model for bridge columns, developed and calibrated using existing experimental data from the shake table tests of a full-scale bridge column. This finite-element model of the bridge column is further expanded to enable evaluation of the axial load-carrying capacity of damaged columns, which is critical for an accurate evaluation of the traffic capacity of the bridge. Existing experimental data from the crushing tests on the columns with earthquake-induced damage support this phase of the finite-element model development. To properly evaluate the bridge's post-earthquake functionality state, realistic traffic loadings representative of different bridge conditions (e.g., immediate access, emergency traffic only, closed) are applied in the proposed model following an earthquake simulation. The traffic loadings in the finite-element model consider the distribution of the vehicles on the bridge causing the largest forces in the bridge columns.

Abstract (sommario):

This paper employs a simple methodology to estimate the potential economic damages of the 2021 earthquake in Haiti. The country registered a magnitude 7.2 earthquake off the South Coast on August 14, 2021, that resulted in 2,248 deaths, 12,763 injured and substantial damages to houses and other infrastructure. An additional 329 persons remain missing. We estimate economic damages using econometric techniques and a dataset on natural disasters across a wide range of countries and over an extended time period. Based on this analysis, damages for the 2021 earthquake in Haiti are estimated to reach US$1.6 billion (9.6 percent of GDP) for a scenario with an impact of 2,500 dead or missing. We also generate confidence intervals on these results. We hope these early estimates will provide a useful input to the ongoing Post-Disaster Risk Assessment (PDNA) and will assist the government and its international partners plan efforts to assist the country in terms of relief and reconstruction.
