Post-earthquake road traversability is a critical factor that affects traffic conditions. Therefore, post-earthquake simulation method considering was proposed in this study. First, the impact ranges of earthquake-induced building collapse and fire spread buildings were analyzed, determined accordingly. Subsequently, flow predicted based on characteristics, micro-level vehicle behaviors simulat...

In this paper, the authors give a brief introduction to the earthquake monitoring system newly developed for two dams of a reservoir in North China. The two embankment dams are 66, 56 meters high and 960, 1008 meters long respectively. One of the dams suffered from severe landslide because of the 1976 Tangshan Earthquake, the design PGA of this site is set to 0.25g. Because of the complexity, i...

Recent years many authors reported thermal anomaly change around epicenter before earthquake. Some researchers tried to predict the earthquake based on the analysis on the temperature anomaly feature by using satellite thermal infrared data. However the infrared radiation can not pass through the thick-layer cloud, so as to hardly achieve the earthquake monitoring. Microwave is also a kind of t...

This paper demonstrates a novel approach for learning about earthquake victims behavioral responses to an emergency situation in the immediate aftermath of an earthquake. Researchers developed an emergency scenario that describes students’ reactions following a magnitude 7.8 earthquake that leads to complications that escalate over eight episodes. Subjects were assigned to scenario simulation g...

A precursory dynamics, motivated by the analysis of recent experiments on solid-on-solid friction, is introduced in a continuous cellular automaton that mimics the physics of earthquake source processes. The resulting system of equations for the interevent cycle can be decoupled and yields an analytical solution in the mean-field limit, exhibiting a smoothing effect of the dynamics on the stres...

Earthquakes are among the most complex terrestrial phenomena, and modeling of earthquake dynamics is one of the most challenging computational problems in science. Computational capabilities have advanced to a state where we can perform wavefield simulations for realistic three-dimensional earth models, and gain more insights into the earthquakes that threaten California and many areas of the w...

Accurate prediction of the intensity and variability of strong ground motions for future large earthquakes depends on our ability to simulate realistic earthquake source models. While there has been considerable progress in characterizing the complexity of earthquake ruptures, recent devastating earthquakes have exhibited rather unexpected behavior. Moderate-size events occurred with surprising...

It is well established that earthquakes are correlated over distances greatly exceeding their source dimension. Recent studies hypothesize for important associated phenomenon: The area over which earthquake activity is correlated varies in time and might grow prior to a large earthquake. This hypothesis is supported by a wealth of observations, computer simulation, and has theoretical interpret...
