This study analyzes damage estimation technique of earthquake disaster. In order to do this, 1) Proposition of current situation analysis and direction of improvement domestic and foreign-related systems of earthquake disaster response system, 2) Establishment and design of research earthquake disaster damage assesment system 3) Analysis and investigation of domestic and foreign-related soil field on damage estimation, 4) Creation of soil liquefaction risk-map and processes method of soil information. When occurred an earthquake, occurs the system rapidly displays seismic intensity distribution and life, structure, lifeline damage estimations. This enables decision makers to support the earthquake disaster response decisions. Eventually, earthquake disaster damages are expected to be reduced significantly.
