We present a virtual reality simulation of an evacuation caused by a trembling earthquake in a secondary school. The simulation is based on artificial intelligence for which a mathematical model is implemented that controls the behavior of agents that represent the school students in the virtual stage. The simulation allows the interaction with the agents on stage by using the gyroscope of a sm...

water is the most essential component for sustaining lives of humans and other living creatures. supplying potable water with adequate residual pressure is a fundamental responsibility of city administration, which they do during normal conditions. but sometimes, abnormal conditions are formed resulting pressure deficient conditions during the daily operations of water distribution networks. th...

[1] Earthquakes are accompanied with mass redistributions and cause changes in gravity field and shape of geoid, an equipotential surface coincident with the mean sea surface. Such coseismic changes were detected by satellite gravimetry after the 2004 Sumatra-Andaman Earthquake, but little has been known on what happens on geoid after the earthquake. Here we report slow postseismic recovery of ...

Broader Impacts. The Southern California Earthquake Center (SCEC) conducts a broad program of earthquake system science that seeks to develop a predictive understanding of earthquake processes with a practical mission aimed at providing society with improved understanding of seismic hazards. In partnership with earthquake engineers, SCEC researchers are developing the ability to conduct end-to-...

We performed simulations of ground motions in Mexico City expected for large earthquakes in the Guerrero seismic gap in Mexico. The simulation method uses as empirical Green's functions the accelerograms recorded in Mexico City during four small to moderate earthquakes (8 Feb. 1988, M s = 5.8; 25 April 1989, M w = 6.9; 11 May 1990, M w = 5.5; and 31 May 1990, Mw = 6.0) in the Guerrero gap.
