There are many damages caused by natural and article disasters. In October 2004 earthquakes hit Niigata-Chuetu in the mid north part of Japan. Under discussion came the terms preparedness, response, recovery and mitigation. Especially during an emergency, it is very important to make correct and quick decisions. Recently, the number of Web-based GISs is increasing and everyone can access GIS data through a Web browser. But, it is difficult to carry out advanced and complex functions because of security problems, for example, editing real-time telecommunication data. We proposed the CMS (Crisis Management System) decision support system for disaster. It is called "Geo-CMS" (Geographic Crisis Management System). It is useful for decision making and disaster mitigation planning such as response, recovery, and correspondence. The Emergency Management Office will share real-time information with other organizations such as the fire department and police office via that system.
