Повний текст джерелаEarthquakes are among the most devastating natural events faced by society. In 2011, just two events, the magnitude 6.3 earthquake in Christcurch New Zealand on February 22, and the magnitude 9.0 Tōhoku earthquake off the coast of Japan on March 11, caused a combined total of $226 billion in economic losses. Over the last decade, 791,721 deaths were caused by earthquakes. Yet, despite their impact, our ability to accurately predict when earthquakes will occur is limited. This is due, in large part, to the fact that the fault systems that produce earthquakes are non-linear. The result being that very small differences in the systems now result in very big differences in the future, making forecasting difficult. In spite of this, there are patterns that exist in earthquake data. These patterns are often in the form of frequency-magnitude scaling relations that relate the number of smaller events observed to the number of larger events observed. In many cases these scaling relations show consistent behavior over a wide range of scales. This consistency forms the basis of most forecasting techniques. However, the utility of these scaling relations is limited by the size of the earthquake catalogs which, especially in the case of large events, are fairly small and limited to a few 100 years of events.
In this dissertation I discuss three areas of earthquake science. The first is an overview of scaling behavior in a variety of complex systems, both models and natural systems. The focus of this area is to understand how this scaling behavior breaks down. The second is a description of the development and testing of an earthquake simulator called Virtual California designed to extend the observed catalog of earthquakes in California. This simulator uses novel techniques borrowed from statistical physics to enable the modeling of large fault systems over long periods of time. The third is an evaluation of existing earthquake forecasts, which focuses on the Regional Earthquake Likelihood Models (RELM) test: the first competitive test of earthquake forecasts in California.

Повний текст джерелаDuring coseismic slip, the energy released by the elastic unloading of the adjacent earth blocks can be separated in three main parts: The energy that is radiated to the earth’s surface (_ 5% of the whole energy budget), the fracture energy for the creation of new fault surfaces and finally, the energy dissipated inside a region of the fault, with finite thickness, which is called the fault gauge. This region accumulates the majority of the seismic slip. Estimating correctly the width of the fault gauge is of paramount importance in calculating the energy dissipated during the earthquake, the fault’s frictional response, and the conditions for nucleation of the fault in the form of seismic or aseismic slip.In this thesis different regularization approaches were explored for the estimation of the localization width of the fault’s principal slip zone during coseismic slip. These include the application of viscosity and multiphysical couplings in the classical Cauchy continuum, and the introduction of a first order micromorphic Cosserat continuum. First, we focus on the role of viscous regularization in the context of dynamical analyses, as a method for regularizing strain localization. We study the dynamic case for a strain softening strain-rate hardening classical Cauchy continuum, and by applying the Lyapunov stability analysis we show that introduction of viscosity is unable to prevent strain localization on a mathematical plane and mesh dependence.We perform fully non linear analyses using the Cosserat continuum under large seismic slip displacements of the fault gouge in comparison to its width. Cosserat continuum provides us with a proper account of the energy dissipated during an earthquake and the role of the microstructure in the evolution of the fault’s friction. We focus on the influence of the seismic slip velocity to the weakening mechanism of thermal pressurization. We notice that the influence of the boundary conditions in the diffusion of the pore fluid inside the fault gouge, leads to frictional strength regain after initial weakening. Furthermore, a traveling strain localization mode is present during shearing of the layer introducing oscillations in the frictional response. Such oscillations increase the spectral content of the earthquake. Introduction of viscosity in the above mode, leads to a rate and state behavior without the introduction of a specific internal state variable. Our conclusions about the role of thermal pressurization during shearing of the fault gouge, agree qualitatively with newly available experimental results.Finally, based on the numerical findings we investigate the assumptions of the current model of a slip on a mathematical plane, in particular the role of the boundary conditions and strain localization mode in the evolution of the fault’s friction during coseismic slip. The case of a bounded domain and a traveling strain localization mode are examined in the context of slip on a mathematical plane under thermal pressurization. Our results expand the original model in a more general context

Earthquake ground shaking is a complex phenomenon since there is no unique way to assess its strength. Yet, the strength of ground motion (shaking) becomes an integral part for predicting the future earthquake performance of buildings using the Performance-Based Earthquake Engineering (PBEE) framework. The PBEE framework predicts building performance in terms of expected financial losses, possible downtime, the potential of the building to collapse under a future earthquake. Much prior research has shown that the predictions made by the PBEE framework are heavily dependent upon how the strength of a future earthquake ground motion is characterized. This dependency leads to uncertainty in the predicted building performance and hence its seismic design. The goal of this dissertation therefore is to employ Bayesian reasoning, which takes into account the alternative explanations or perspectives of a research problem, and propose robust quantitative methods that aid IM selection and ground motion selection in PBEE The fact that the local intensity of an earthquake can be characterized in multiple ways using Intensity Measures (IM; e.g., peak ground acceleration) is problematic for PBEE because it leads to different PBEE results for different choices of the IM. While formal procedures for selecting an optimal IM exist, they may be considered as being subjective and have multiple criteria making their use difficult and inconclusive. Bayes rule provides a mechanism called change of perspective using which a problem that is difficult to solve from one perspective could be tackled from a different perspective. This change of perspective mechanism is used to propose a quantitative, unified metric for rating alternative IMs. The immediate application of this metric is aiding the selection of the best IM that would predict the building earthquake performance with least bias. Structural analysis for performance assessment in PBEE is conducted by selecting ground motions which match a target response spectrum (a representation of future ground motions). The definition of a target response spectrum lacks general consensus and is dependent on the analysts’ preferences. To encompass all these preferences and requirements of analysts, a Bayesian target response spectrum which is general and flexible is proposed. While the generality of this Bayesian target response spectrum allow analysts select those ground motions to which their structures are the most sensitive, its flexibility permits the incorporation of additional information (preferences) into the target response spectrum development. This dissertation addresses four critical questions in PBEE: (1) how can we best define ground motion at a site?; (2) if ground motion can only be defined by multiple metrics, how can we easily derive the probability of such shaking at a site?; (3) how do we use these multiple metrics to select a set of ground motion records that best capture the site’s unique seismicity; (4) when those records are used to analyze the response of a structure, how can we be sure that a standard linear regression technique accurately captures the uncertainty in structural response at low and high levels of shaking?

Повний текст джерелаEarthquakes are the results of rapid slip on active faults loaded in stress by the tectonic plates motion. It is now establish - at least for large earthquakes - that the distribution of this rapid slip along the rupturing faults is heterogeneous. Imaging the complexity of such slip distributions is one the main challenges in seismology because of the potential implications on understanding earthquake genesis and the associated possibility to better anticipate devastating shaking and tsunami. To improve the imaging of such co-seismic slip distributions, three axes may be followed: increase the constraints on the source models by including more observations into the inversions, improve the physical modeling of the forward problem and improve the formalism to solve the inverse problem. In this PhD thesis, we explore these three axes by studying two recent major earthquakes: the Tohoku-Oki (Mw 9.0) and Sumatra-Andaman (Mw 9.1-9.3) earthquakes, which occured in 2011 and 2004 respectively

Taiwan is located in the boundary of the Eurasian Plate and Philippine Sea Plate. Because of the plate extrusion, there is high seismicity rate over the past few years. Therefore, in order to achieve the purpose of disaster prevention and mitigation, seismic factors should be taken into account in the design of the building to reduce the damage and harm caused by the earthquake. The purpose of this paper is to apply the Extreme Value Theory(EVT)to estimate the maximum credible magnitude of each seismic zone in Taiwan. The estimated maximum credible magnitude mainly included the deterministic procedure and probabilistic procedure. In the past, the deterministic procedure was often used to estimate the maximum credible magnitude. The commonly used method is the largest earthquake magnitude of the historical record plus 0.5. However, it is a subjective value, so there is high uncertainty. The extreme value analysis used in this study is a probabilistic procedure. The probabilistic procedure is more objective compared with the deterministic procedure because it used a more objective method to estimate the maximum credible magnitude. This study collected the seismic data from 1978 to 2017 and used the Weibull distribution to model the observation. Furthermore, this study used the Chi-square test to test the hypothesis if the observation follows the Weibull distribution. Finally, the maximum credible magnitude calculated by the EVT(different time periods and different tail of probability distributions in extreme value theory)is compared with the value evaluated by the methods of maximum historical magnitude plus 0.3 and plus 0.5 in the deterministic procedure. Compared with the plus 0.3 method and the plus 0.5 method, EVT can directly evaluate the different time periods and the magnitude of different percentiles. The most important is that the extreme value theory takes the time factor into account. While the traditional plus 0.3 method and the plus 0.5 method do not. Therefore, using EVT is more objective and practical for predicting the magnitude of earthquakes.

In recent years, the government and educational circles put into a great deal of manpower, material resources on the disaster prevention research, like a disaster prevention office and the domestic affairs mansion National Fire Administration, all put emphasis on the damage of earthquake disaster building valuation. The accomplishment is splendid, and had great help on evaluating and counting the loss of the earthquake estimating in early days. Because the earthquake has the variation, the factors that cause the destructions of the building after shakes are many, like the ground moves the parameter, the building structure, the site data and construction quality etc. Thus, to build up the building reasonable damage rate valuation, is now still a worthy development topic to study continuously. This research makes use of the faintness to gather the theories, considering its indetermination factor, gathering traditional definitely to expand to go to the faintness to gather medium, make use of the belonging function to describe the spread of one building damage, calculate the probability of the building damage, and with the experience rule- return to the analytical method to compare, and prove that the misty theories can be used in estimating the building damage rate, and the calculated results are reasonable and familiar with the actual loss data. Through the establishment of the building damage rate, providing the disaster situation estimation, and can be the instant contingency when earthquake happened and defend the reference of the relief programming at ordinary time.

The purpose of this study was to explore the effect of earthquake simulation activities on people’s willingness to prevent earthquake disasters. It was based on Experimental Marketing Theory. The study was designed to use questionnaires and Google Forms for data collection. The study used SPSS 20 to analyze survey questions and showed these research instruments were valid and also reliable. There were 216 valid questionnaires and 24 invalid questionnaires in formal study through pretest. These data was analyzed by a descriptive statistics, Pearsons relationship, and Regression Analysis.The study aim to explore the relationship between factors: experiential marketing, experiential value, and behavioral intention.The first , the experiential marketing was divided into five dimensions: sense experience, feel experience, think experience, act experience and relate experience. The second, the experiential value was consisting of functional value, emotional value, and social value. The third, behavioral intention was defined as a persons perceived likelihood or "subjective probability that he or she will engage in a given behavior".The result indicated that the participants knew the value of earthquake disaster prevention through these experiences and the experiential values improved behavioral intentions of the participants. To further illustrate the point, the emotional value had a stronger effect on behavioral intentions.

Located on the Eurasia plate and the Philippine marine plate to push with the lasting, where earthquakes happen frequently, Taiwan, due to particularity with complicated geography character, was attack by earthquakes. Earthquake is a natural proceeding in which the earth releases energy. It is not the manpower that can be controlled, through verifying that relation with a certain level of education in groundwater level change and the earthquake appears. Besides, there are well network observing groundwater changes in Taiwan. For observing groundwater, we get certain advantage. Searching how to decrease the damage caused by earthquakes, we must study the correlation between groundwater and earthquakes. Observe the monitoring station of Nabal and Liujar as the research object, at the Jarnan strong shock earthquake groundwater network in this research. In order to probe the earthquake incident, whether produce the unusual behavior to the groundwater level, make using observed of groundwater level time sequence to analyze the change amount of the groundwater level clicked, in time before and after an earthquake attack. In order to prevent the earthquake incident from being influenced by incidents, such as ground tide , rainfall ,etc. Causing the wavelet analyse obtain the accurate result, the unusually high frequency be unable diagnose. The Artificial Neural Network(ANN) is so utilizing to detrend of rainfall, ground tide, and irregular signal, etc. Detrend of morning and evening tides, rainfall time series through kinds of ANN. Using the Wavelet theory to explore the long-time groundwater level examines the amount layer of structure separately, and uses the Wavelet transform and calculate the Wavelet coefficient, can assess various mixing interweaving kinds of the groundwater level signal by calculation of Wavelet coefficient value, resolve into and distinguish layer or different frequency block signals at differently level, and then, using Wavelet shrinkage method by Donoho and Johnstone, to estimating and examining the Wavelet coming out in development of the signal. Choose a suitable critical value, to clipping the high-frequency Wavelet coefficient. And then, using threshold to shrink wavelet coefficient, and clipping out the approximation function and the detail function of underground water level attack by just earthquake. Taking that obviously of this point out groundwater level appear frequency unusual time, therefore will contribute to reducing natural disasters, will lengthen and take refuge and reflect time.

Знайти повний текст джерелаIn April and May 2015 Nepal suffered two massive earthquakes of 7.5 and 6 5 magnitudes in the Richter scale, killing 8856 and injuring 22309. Two years later in September 2017, Puerto Rico underwent the Category 5 Hurricane Maria, killing an estimate of 800 to 8000 people and displacing hundreds of thousands of Puerto Ricans (Kishore et al., 2018). This dissertation project is the comparative study of Nepal’s and Puerto Rico’s networked communities, their actors, participants (Potts, 2014), and the users (Ingraham, 2015; Johnson, 1998) who used crisis communication practices to address the havoc created by the disaster. Using a mixed-methods research approach and with framework created with the Assemblage Theory (DeLanda, 2016), I argue that disasters create situations in which various networked communities are formed into transnational assemblages along with an emergence of innovative digital technical and professional communication practices.

The Copula model is applied in the thesis in order to analysis the correlation between loss ratios for the earthquake insurance which includes the residential earthquake insurance, the commercial earthquake insurance, and the factory earthquake insurance. In the empirical study, firstly, we analysis the correlation for the right tail under each of two datasets by using three types of Copula that are Clayton Copula, Frank Copula, and Gumbel Copula. Secondly, we search for the appropriate model for the overall loss ratio for these three earthquake insurance based on the Gaussian Copula and the Student’s t Copula. In the simulation study, we construct two series of loss ratio data with and without the property of independence, for the loss ratio data without the independence, the Student’s t Copula specification is exercised, and calculate its’ total losses. The Value at Risk (VaR) and the Conditional Tail Expectation (CTE) are two criteria for decision. According to the result, the value of total loss calculated from the loss ratio data with correlation acquires higher VaR and higher CTE value. We might suggest that when pricing or making decision on risk aversion, insurance company could take the loss ratio correlation into consideration.

Повний текст джерелаThe near-field ground motion signatures associated with sub-Rayleigh and supershear ruptures are investigated using the laboratory earthquake experiment originally developed by Rosakis and co-workers (Xia et al., 2004, 2005a; Lu et al., 2007; Rosakis et al., 2007). Heterodyne laser interferometers enable continuous, high-bandwidth measurements of fault-normal (FN), fault-parallel (FP), and vertical (V) particle velocity ``ground motion" records at discrete locations on the surface of a Homalite-100 test specimen as a sub-Rayleigh or a supershear rupture sweeps along the frictional fault. Photoelastic interference fringes, acquired using high-speed digital photography, provide a synchronized, spatially resolved, whole field view of the advancing rupture tip and surrounding maximum shear stress field.
The first phase of experimental investigations examine and verify the ground motion signatures of supershear ruptures. Experimental results demonstrate that a shear Mach front produced by a stable supershear rupture is characterized by a dominant FP velocity component. The situation is shown to reverse in the sub-Rayleigh rupture speed regime whereby the FN particle velocity component dominates the ground motion record. Additional distinguishing particle velocity signatures, consistent with theoretical and numerical predictions, and repeatedly observed in experimental records are, (1) a pronounced peak in the FP velocity record induced by the leading dilatational field, which sweeps the measurement station in advance of the shear Mach front, and (2) a pronounced velocity swing in the FN record associated with the arrival of a trailing Rayleigh sub-Rayleigh (secondary) rupture, which follows the arrival of the shear Mach front. Analysis of the particle velocity records also confirms 2D steady-state theoretical predictions pertaining to the separation, attenuation, and radiation partitioning of the shear and dilatational portions of the rupture velocity field components.
The second phase of our experimental investigations re-examine the 2002, Mw7.9, Denali fault earthquake and the remarkable set of near-source ground motion records obtained at (PS10), located approximately 85 km east of the epicenter and just 3 km north of the fault along the Alaska pipeline. Motivated by the analysis and interpretation of these records by (Ellsworth et al., 2004; Dunham and Archuleta, 2004, 2005), we attempt to mimic the Denali strike-slip rupture scenario and replicate the PS10 ground motion signatures using a laboratory earthquake experiment. The experiments feature a left-to-right (west-to-east) propagating right lateral rupture within a Homalite-100 test specimen with particle velocity data collected at a near-field station situated just above (north of) the fault. Both sub-Rayleigh and supershear laboratory earthquake experiments are conducted using the Denali PS10 configuration in order to compare and contrast the resulting particle velocity signatures. Supershear laboratory records capture all of the prominent features displayed within the PS10 ground motion records. Noted velocity signatures are correlated to the location of the rupture fronts and their noted arrival times in the synchronized photoelastic image sequence. Scaling relationships are also presented which transform the laboratory records through six orders of magnitude in time, to match the scale of the PS10 ground motion records. The strong correlation between the scaled experimental records and the actual PS10 ground motion records support the hypothesis that the Denali strike-slip fault exhibited a supershear burst.
Finally, we present a 2D steady state, stress-velocity formulation that relates the FP and FN particle velocity records measured close to the fault, to the evolution of the stress tensor at the same location. A locally steady-state condition is assumed within a restricted time interval in order to invoke these relationships and estimate the dynamic stresses, σxx(t) and τ(t), at the near-fault station. Dynamic stress measurements enable a new class of friction investigations using the laboratory earthquake configuration. Experimental findings are presented, which capture the temporal and spatial distributions of σxx and τ, evolution of the dynamic friction coefficient, and velocity weakening behavior of a supershear slip-pulse.
