Development of Citzen-Oriented Web-Based Seismic Hazard and Risk Maps and Their Assessment

Abstract

As seismic hazard and risk information for the citizens, seismic hazard maps that indicate intensity of shake are made for example by local governments. For the next step, authors made seismic risk map for residential building damage. Based on this map, we developed the web-based seismic hazard and risk map. The purpose of the web-based map is that the citizen recognize his/her own seismic hazard and risk problem by showing detailed map of estimation on the seismic intensity and the building damage risk where the citizen lives. The questionnaire survey on the web-based map was conducted in order to research the effect of the citizens' disaster awareness and disaster prevention behavior which were caused by the web-based map.
