Toland, Joseph Charles. "A Model for Emergency Logistical Resource Requirements| Supporting Socially Vulnerable Populations Affected by the (M) 7.8 San Andreas Earthquake Scenario in Los Angeles County, California." Thesis, University of Southern California, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10936557.
Повний текст джерелаFederal, state and local officials are planning for a (M) 7.8 San Andreas Earthquake Scenario in the Southern California Catastrophic Earthquake Response Plan that would require initial emergency food and water resources to support from 2.5 million to 3.5 million people over an eight-county region in Southern California. However, a model that identifies locations of affected populations—with consideration for social vulnerability, estimates of their emergency logistical resource requirements, and their resource requirements over time—has yet to be developed for the emergency response plan.
The aim of this study was to develop a modeling methodology for emergency logistical resource requirements of affected populations in the (M) 7.8 San Andreas Earthquake Scenario in Southern California. These initial resource requirements, defined at three-days post-event and predicted through a probabilistic risk model, were then used to develop a relative risk ratio and to estimate resources requirements over time. The model results predict an “at-risk” population of 3,352,995 in the eight-county study region. In Los Angeles County, the model predicts an “at- risk” population of 1,421,415 with initial requirements for 2,842,830 meals and 4,264,245 liters of water. The model also indicates that communities such as Baldwin Park, Lancaster-Palmdale and South Los Angeles will have long-term resource requirements.
Through the development of this modeling methodology and its applications, the planning capability of the Southern California Catastrophic Earthquake Response Plan is enhanced and provides a more effective baseline for emergency managers to target emergency logistical resources to communities with the greatest need. The model can be calibrated, validated, generalized, and applied in other earthquake or multi-hazard scenarios through subsequent research.

Повний текст джерелаSeismic hazard assessment can be performed following a neo-deterministic approach (NDSHA), which allows to give a realistic description of the seismic ground motion due to an earthquake of given distance and magnitude. The approach is based on modelling techniques that have been developed from a detailed knowledge of both the seismic source process and the propagation of seismic waves. This permits to define a set of earthquake scenarios and to simulate the associated synthetic signals without having to wait for a strong event to occur. NDSHA can be applied at different geographic scale with different detail levels of modelling. At local scale the source and site characteristics can be take account, whereas at the regional scale seismograms at the nodes of a regular grid are computed. Finite fault simulation is needed to compute realistic ground motions close to a ruptured fault. No reasonable deterministic prediction for many details of a future fault motion can be expected and their variability can be treated in practice only from a statistical viewpoint. Therefore, their effect is simulated through Monte-Carlo approach. To test the accuracy of the method, the L’Aquila earthquake occurred on April 6, 2009 has been modelled. The use of a realistic model for the representation of the extended fault introduces a stochastic element in NDSHA. So the variability due to the stochastic component of seismic source has been evaluated. In standard NDSHA at regional scale, seismograms are computed for an upper frequency content of 1 Hz. The use of a more realistic source model than the scaled point source that takes account of effective duration of rupture process allowed to extend the maximum frequency of computation of seismograms of national scale maps to 10 Hz. A first estimation of uncertainty due to the random representation of the source in national scale maps has been obtained by parametric tests on EU-India Grid infrastructure. NDSHA defines the hazard as the maximum ground motion at the site and it does not supply information about the frequency of occurrence of the expected ground motion. The standard procedure of NDSHA has been modified here, to take into account the additional information of recurrence. The introduction of recurrence estimates in NDSHA allows the generation of ground motion maps for specified return periods that permits a straightforward comparison between the NDSHA and the PSHA maps. Furthermore the map of the recurrence has been associated with standard map of ground motion.
La valutazione della pericolosità sismica può essere effettuata seguendo un approccio neo-deterministico (NDSHA) che permette di dare una descrizione realistica del moto del suolo dovuto a un terremoto di data distanza e magnitudo. L’approccio è basato su tecniche di modellazione che sono state sviluppate da una conoscenza dettagliata sia della sorgente che della propagazione delle onde sismiche. Questo permette di definire un set di terremoti di scenario e di simulare i segnali sintetici associati senza dover aspettare l’accadimento di un forte evento. La metodologia neo-deterministica può essere applicata a diverse scale geografiche cui corrispondono differenti livelli di dettaglio nella modellazione. A scala locale è possibile tenere conto delle caratteristiche specifiche della sorgente e del sito considerati, mentre a scala regionale vengono calcolati i sismogrammi ai nodi di una griglia regolare. Per simulare in modo realistico il moto del suolo in prossimità di una faglia è necessario usare un modello di sorgente estesa. Molti dettagli del processo di rottura sulla sorgente non possono essere predetti in modo deterministico e la loro variabilità può essere trattata solo da un punto di vista statistico. Di conseguenza i loro effetti vengono simulati attraverso una approccio Monte-Carlo. Per testare l’accuratezza del metodo è stato modellato il terremoto dell’Aquila del 6 aprile 2009. L’uso di un modello realistico di sorgente per la rappresentazione della sorgente estesa introduce un elemento stocastico nel metodo neo-deterministico. Si è quindi valutata la variabilità dei valori di picco dovuta alla modellazione della sorgente. Nella metodologia neo-deterministica scala regionale i sismogrammi vengono calcolati con una frequenza massima di 1 Hz. L’uso di un modello di sorgente piu` realistico rispetto a quello della sorgente puntiforme in grado di tener in conto dell’effettiva durata del processo di rottura ha consentito di estendere la frequenza massima di calcolo dei sismogrammi delle mappe di pericolosità nazionali a 10 Hz. Una prima stima dell’incertezza legata alla simulazione stocastica della sorgente sulle mappe a scala nazionale è stata ottenuta con l’uso di test parametrici condotti utilizzando l’infrastruttura informatica EU-India Grid. Il metodo neo-deterministico definisce la pericolosità come il massimo scuotimento al sito e non fornisce alcuna informazione sulla ricorrenza del moto del suolo atteso. La procedura è stata modificata per tener conto dell’informazione aggiuntiva della ricorrenza. In questo modo è stato possibile generare delle mappe di scuotimento per specifici periodi di ritorno che consentono un diretto confronto con le mappe probabilistiche. Inoltre alle mappe di massimo scuotimento sono state associate le rispettive mappe di ricorrenza del moto del suolo.

Повний текст джерелаWhen an earthquake occurs, survivors start to evacuate. Especially in historical centres, their safety is connected to the surrounding environment but several factors can increase their difficulty to locate and reach safe zones. Furthermore, the scarce familiarity with the place, the emergency plan and the safe paths, drastically raise the probability they can be involved into fatalities while trying to get themselves safe. Studies about risk evaluation, emergency planning and evacuation management had a large development but they have been focused especially for fire emergency and indoor environment. Only recently, specific guidelines for earthquake emergency in urban scenarios have been produced. However, they are quite simplified approaches focusing on rescuers’ perspective, not effectively supporting survivors. In a such context, the ability to autonomously evacuate and gain safe place, also called ‘self-help’, is the main resource survivors can carry out. The current work starts analysing the consolidated literature, then, new methodologies for urban emergency planning and post-earthquake evacuation in historical centres are proposed. A performance-based approach is adopted to evaluate the criticalities deriving from the men-environment interactions and to offer possible solutions. To this aim, several fields of study are defined and new methodologies and tools are offered where necessaries. The proposed methods, applied to a case study, are tested using a behavioural simulation software specialized for earthquake emergency. Key Performance Indicators are adopted to quantify the evacuation performances and evaluate the effectiveness of the proposed planning and guidance methods. Combining the proposed studies with traditional methods could be useful to emergency planners during the analyse and designing phases. Furthermore, it can be a considerable optimization practice in case of limited resources, or in scenarios with relevant constrains as the historical ones.

One of the most important issues of the recent development of seismology and earthquake engineering is the capability to predict strong ground motion for future large earthquake based on state-of-the-art knowledge and observations. However, it is very difficult to achieve realistic ground motion response by numerical simulation due to the poor resolution of underground structure and high computational consuming. In this study, we present three approaches to extend the simulating frequency band and to establish the feature of realistic strong ground motion pattern. There are two major parts in this study. First part focuses on the developments and tests of the three approaches to realize broadband ground motion simulation. The three approaches are (1) Hybrid method, (2) Frequency ratio method and (3) High frequency numerical simulation. These three approaches are applied on the 2010 Jiashian (M6.4) and 2009 Nanto (M5.13) earthquakes. In the second part, the hybrid broadband simulation technique is considered to apply on Hengchun scenario earthquake. Results indicate that using hybrid method with characteristic source model approach can provide a physics-based simulation result to predict strong ground motion of large earthquake that could occur in the future. The long term goal of this study will be to give contributions to the earthquake mitigation and seismic hazard assessment.

The Longitudinal Valley (LV) in the eastern Taiwan is considered as the suture zone between the Eurasia Plate and the Philippine Sea Plate. Thousands of earthquakes are occur in this area every year. The Longitudinal Valley Fault (LVF) is a seismically active structure, which is located along the LV. During the time period from October to December in 1951, lots of large earthquakes occurred between Hualien and Taitung area, including four major earthquakes (M > 6.9) and thousands of aftershocks. This earthquake series is known as the Longitudinal Valley Earthquake sequence. Coseismic surface rupture with a total length of approximate 90 km were observed along LV. In order to understand the characteristics of source rupture and resultant strong ground motion, this study is comprised of two different parts. In first part, we reconstructed the source model and strong ground motion time history of this earthquake sequence. Inversion of the coseismic displacement data was first conducted. Based on the inverted slip distribution, we performed 3D forward simulation using the Spectral Element Method. Therefore, the second part of the thesis focuses on ground motion prediction for scenario earthquakes. We performed wave propagation simulation with ten stochastic rupture scenarios and examined the results collectively. The numerical simulation results showed that the PGA larger than 250 cm/s2 distributed along LV in eastern Taiwan in all cases. If the rupture started in the middle of LVF, PGA larger than 80 cm/s2 could be detected in the entire island. In the particular stochastic source rupture models, the PGA might be larger than expected in some places far from LVF due to source radiation and directivity effect, such as Taipei basin, Ilan and southern part of Taiwan. The models we presented in this thesis for both historical and scenario events can serve as reference for future in-depth seismotectonic studies and hazard assessment.

The Ji-Ji earthquake, which resulted in serious damage of public properties, took place in the middle part of Taiwan. Haz-Taiwan is an earthquake loss estimation and scenario simulation system modified from HAZUS, a system used in the US. Due to the difference in national conditions, divisions of administrative boundaries, and the lack of related databases, the Haz-Taiwan system must be revised. Taiwan Earthquake Loss Estimation System (TELES) is developed by the National Center for Research on Earthquake Engineering (NCREE) to replace Haz-Taiwan, and is used to analyze the state of damage caused by earthquakes in the Taiwan area. However, the lifeline module has not yet been implemented in TELES. After the Ji-Ji earthquake, the fragility analysis of buried pipelines focused on the disaster area. Some of the analysis has been completed, such as damage of potable water pipelines, natural gas pipelines, and wastewater pipelines. The results can be used to evaluate the relationship between the damage of pipelines and the magnitude of earthquakes. This study is the first of its kind to incorporate the damage functions of water pipelines into a rapid earthquake loss estimation and scenario simulation system of lifelines. The rapid earthquake loss estimation and scenario simulation system of lifelines can be used to simulate the state of damage of water pipelines caused by earthquakes and the results can be used for disaster preparedness. When a real earthquake occurs, the system can be activated automatically by an e-mail from the Central Weather Bureau to calculate the possible damage distribution, and forward the results to decision makers and emergency crew via e-mails and SMS messages. Thus, the response time can be reduced and more property loss can be prevented.

Earthquake is one of the major natural disasters caused massive destruction in the Taipei metropolitan area. Sanchiao fault is a western boundary fault of the Taipei basin located in northern Taiwan, close to the densely populated Taipei metropolitan area. Combined with the marine and terrestrial parts, the total fault length of Sanchiao fault could over 50 kilometers. For the past 400,000 years, the bedrock of Tertiary sedimentary basin continued to subside due to the activity of the Sanchiao fault, resulting the thickness of Quaternary sediments of the basin up to 700 meters in the northwest side. Displacement measured by GPS in northern Taiwan, on both sides of the Sanchiao fault, revealed up to 5-8 mm per year of movement. It may be reactivated in the future. This study is based on the “RECIPE” for predicting strong ground motion proposed by Kojiro Iriura and Hiroe Miyake (2011). The characteristic source parameters include: fault length, rupture area, seismic moment, the fault plane momentum slip, asperity and propagation pattern of rupture etc. Based on these assumptions in the characteristic source model, Sanchiao fault has been inferred to have the potential to produce an earthquake with moment magnitude (Mw) larger than 7.0. Three-dimensional seismic simulation using Spectral-Element Method (SEM), the 3D spectral-element method simulation results indicate that Peak Ground Acceleration (PGA) is significantly stronger along the fault trace. The basin effects play an important role when wave propagates in the Taipei basin which cause seismic wave amplified and prolong the shaking for a very long time. In order to increase the universality and breadth of simulation study, we assumed multiple of possible earthquake scenarios. Among them, rupture direction from north to south of the situation is comparatively serious. Owing to the shock direction as well as the basin effect, Taipei basin has high PGA, especially on the northwest side. This clearly shows that it is closely related to the basin sediments. Through statistical analysis, the results of this numerical simulation will provide important earthquake disaster and earthquake engineering reference data.

The research was aimed at the urban fire of Taipei city. By using the factors of structure、distance、angle and cover, the building types and distribution in Wanhua area、Jungjeng area and Daan area are investigated to review the possibility of the urban fire exposure spreading in Taipei city. Now, the fire-resistance is the main building type in blocks of Taipei. The ratio of the fire-resistance in the investigated area is over 70% before 1945 and after 1945 is over 90%. Therefore, the radiation exposure spreading fire from the building’s opening parts is the main reason in Taipei city. The exposure spreading fire happened more easily in the blocks of highly concentrated wood structure. By using the frame coefficient, if only considering the exposure spreading fire in the vertical direction, it wouldn’t spread road of 6m、8m and 10m between the blocks. Because of the continuous combustible in horizontal, highly concentrated commercial using area is probably results in the fire spreading, and will increase the peril of the across buildings through the opening parts. Therefore, the character of combustible、the fire spread speed and the wind velocity around the opening parts are the key point whether the radiation exposure spreading will happening or not. Combine all the result of analysis, the danger area of higher fire spreading possibility is delimited in the blocks and the results can be provided for the urban fire compartment.
(9375209), Cristhian Lizarazo Jimenez. "IDENTIFICATION OF FAILURE-CAUSED TRAFFIC CONFLICTS IN TRACKING SYSTEMS: A GENERAL FRAMEWORK." Thesis, 2020.
Знайти повний текст джерелаTraffic conflicts are one of the most widely adopted surrogate measures of safety because they meet the following two conditions for crash surrogacy: (1) they are non-crash events that can be physically related in a predictable and reliable way to crashes, and (2) there is a potential for bridging crash frequency and severity with traffic conflicts. However, three primary issues were identified in the literature that need to be resolved for the practical application of conflicts: (1) the lack of consistency in the definition of traffic conflict, (2) the predictive validity from such events, and (3) the adequacy of traffic conflict observations.
Tarko (2018) developed a theoretical framework in response to the first two issues and defined traffic conflicts using counterfactual theory as events where the lack of timely responses from drivers or road users can produce crashes if there is no evasive action. The author further introduced a failure-based definition to emphasize conflicts as an undesirable condition that needs to be corrected to avoid a crash. In this case, the probability of a crash, given failure, depends on the response delay. The distribution of this delay is adjusted, and the probability is estimated using the fitted distribution. As this formal theory addresses the first two issues, a complete framework for the proper identification of conflicts needs to be investigated in line with the failure mechanism proposed in this theory.
The objective of this dissertation, in response to the third issue, is to provide a generalized framework for proper identification of traffic conflicts by considering the failure-based definition of traffic conflicts. The framework introduced in this dissertation is built upon an empirical evaluation of the methods applied to identify traffic conflicts from naturalistic driving studies and video-based tracking systems. This dissertation aimed to prove the practicality of the framework for proactive safety evaluation using emerging technologies from in-vehicle and roadside instrumentation.
Two conditions must be met to properly claim observed traffic events as traffic conflicts: (1) analysis of longitudinal and lateral acceleration profiles for identification of response due to failure and (2) estimation of the time-to-collision as the period between the end of the evasion and the hypothetical collision. Extrapolating user behavior in the counterfactual scenario of no evasion is applied for identifying the hypothetical collision point.
The results from the SHRP2 study were particularly encouraging, where the appropriate identification of traffic conflicts resulted in the estimation of an expected number of crashes similar to the number reported in the study. The results also met the theoretical postulates including stabilization of the estimated crashes at lower proximity values and Lomax-distributed response delays. In terms of area-wide tracking systems, the framework was successful in identifying and removing failure-free encounters from the In-Depth understanding of accident causation for Vulnerable road users (InDeV) program.
This dissertation also extended the application of traffic conflicts technique by considering estimation of the severity of a hypothetical crash given that a conflict occurs. This component is important in order for conflicts to resemble the practical applications of crashes, including the diagnostics of hazardous locations and evaluating the effectiveness of the countermeasures. Countermeasures should not only reduce the number of conflicts but also the risk of crash given the conflict. Severity analysis identifies the environmental, road, driver, and pre-crash conditions that increase the likelihood of severe impacts. Using dynamic characterization of crash events, this dissertation structured a probability model to evaluate crash reporting and its associated severity. Multinomial logistic models were applied in the estimation; and quasi-complete separation in logistic regression was addressed by providing a Bayesian estimation of these models.

We used seismic station array on the margin of the Western Pacific to examine the controlling factors of earthquakes in the Izu-Bonin-Mariana subduction zone to excite T waves. The observed excited T waves in turn were used to investigate the decisive parameters for receiver-side acoustic-to-elastic conversion, in a quantitative fashion by the Gamma calculation. Having examined earthquakes in 2005, 17 out of 48 are T-excited events. We have discovered a preferential source-receiver pair for observations of T waves, namely, earthquakes in the southern Mariana Arc as recorded by stations in East Taiwan coastline. Additionally, the T-excited events correlate strongly with normal faulting type of earthquakes. While the strong curvature of the mid-SOFAR isobaths in the South Mariana Arc and the nearly perpendicular incidence to the receiver shoreline of earthquakes herein are conceptually attributed the preferential pair, the correlation with normal-faulting earthquakes needs to be cautiously examined by further studies. On the receiver side, the steeply dipping slopes of the East Taiwan coasts act as efficient interfaces for acoustic-to-elastic conversion. The converted T-waves can be recorded by stations even 50 km inland. The angles between incidence and receiving shoreline also determine the efficiency of receiver-side conversion.
