Recently the frequency of earthquake occurrence raised and the loss of both life and property due to large scale earthquakes such as Kyoung-ju and Pohang increased. It is needed to be equipped with disaster forecasting and responding ability by using intelligent disaster response and decision support systems. SOC facilities are especially very important due to not only the means of support for social and industrial activities in normal situation but also the means of protection of life and property during disaster occurrence. Therefore, the authors in this paper evaluated the level of importance and risk due to earthquake on facilities with GIS mapping data of Pohang city. As well they adopted its results in disaster response algorithm combining with boring information in order to make a more efficient disaster decision support system. The results of this paper will be a foundation of developing an advanced, systematic database inventory for disaster response and decision support systems in various disaster areas, as well as contribute to enhance the disaster response ability of city managers and experts with proactive EAP of life and property protection.
