Virtual Reality and Simulation of the Earthquake-Induced Urban Hazard Based on Artificial Neural Network and COMGIS Technique

Abstract

A method for virtual reality and simulation of the earthquake-induced urban hazard is developed using an artificial neural network (ANN) and components geography information system (COMGIS). The research shows that: a) COMGIS technique is an effective method to realize the coupling of the GIS module and hazard simulation module, b) The site earthquake influence field under the scenario earthquake can be simulated by utilizing the external commercial program-SHAKE91 c) ANN toolbox in Matlab is modularized to extend the virtual reality and simulation function of the earthquake-induced urban hazard, d) by GIS module, the simulated results can be perfectly matched with the spatial information. Thus the potential earthquake-induced urban hazard can also be simulated by assuming the exact earthquake magnitude
