A Decision Supporting System for Earthquake Disaster Mitigation

The earthquake disaster was a vast risk for a sustainable and harmonious societal and economic development, so, it was effective methods to build a decision supporting system for earthquake disaster mitigation and preparation stratagem. A typical decision support system for Earthquake disaster mitigation was introduced in this paper. The principle, design criteria, structure, functions and application of the system were described herein. This system based on Geographical Information System and Artificial Intelligence, consists of below several parts: earthquake hazard analysis, lifeline system performance analysis, kinds of building earthquake damage forecasting, post-earthquake emergency response aided-decisions and earthquake information instant publishing. In this system, there were more than 100 coverages and 36 analytical models. These coverages covered almost all related data to meet the needs of earthquake disaster mitigation and risk assessment, including recorded earthquakes, seismic tectonic zones, intensity distribution of historic earthquake, soil profiles, characteristics of buildings, distribution of citizens, important lifeline systems, earthquake rescuing experience and knowledge, etc. These analytical modules could be used to generate isoseismals of earthquake, estimate site effects, forecast the failure possibility of slope and the damage bound of landslide triggered by earthquake, evaluate performance, damage and losses of building and lifeline system, assess the toll of death and injured, and provided the decision-making for rescue, relief, evacuation.
