Constructions of earthquake scenarios based on virtual simulations

Abstract

The earthquake is an emergency with low probability and high risk. Constructing a real earthquake disaster scene can be used for earthquake emergency exercises, and timely inspection of escape, self-rescue and mutual rescue, and government decision-making deficiencies. Conducting the earthquake exercises under realistic conditions is not easily realized. Compared to the previous methods, the method based on virtual simulations is considered as one of the best effective ways. In this study, we employ the virtual simulations to construct earthquake disaster scenarios. The disaster scenarios immerse people in a virtual environment, where they learn to respond to earthquakes. We demonstrated the system architecture and its components, adopted 3dMAX and virtual simulations to reconstruct the modeling and reproduction of the regional topography, the city and the roads, bridges, hospitals, and building collapses in disaster areas. Virtual reality technology is used to realize the construction of the virtual city. Tests show that the system has good stability and effect, and reached the target set by the system.
