Research of Virtual Simulation Scenario Editor for Earthquake Tabletop Exercise

Abstract

Earthquake is a small probability of unexpected events. Most of the emergency management personals did not experience the earthquake. They may cause flaws in the post-earthquake emergency response process, if they do not take part in earthquake emergency exercise. Traditional tabletop exercise, however, cannot provide a relatively realistic earthquake disaster scenes and vivid emergency background, so they need the virtual simulation exercises and drills for emergency management personnel to provide a real disaster site that is very similar to a drill. This paper presents system structure, function composition, scenario editing process of virtual reality simulation of earthquake emergency exercise and discusses a scenario editor based on OSG. Scenario Editor of earthquake emergency can control the drill and quickly rebuild the drill scene and improve emergency management personnel to design urban 3D scenes and earthquake and secondary disasters events.
