Predicting Tsunami Inundated Area and Evacuation Road Based On Local Condition Using GIS

Abstract

Tsunami is very important phenomena in the disaster management problems. Based on the tsunami was occurred in Aceh Indonesia on December 26, 2004 was killed more than 200.000 peoples, the tsunami disaster management become very important to study. One of the studies is disaster management due to the tsunami hazard along shoreline of southern beach of East Java Province Indonesia. According to the geological data, area of east Java Ocean has high potential of earthquake. The history shows that there are many time tsunami occurred in east Java. In 1994 the tsunami was occurred in Kabupaten Banyuwangi (Banyuwangi Regency) beach and was killed 240 peoples. From this initial study, one of the area predicted as dangerous area for the tsunami is Pacitan city. To minimize the effect of tsunami hazard, the tsunami disaster management study was done for Pacitan city. In this research predicting of inundation area caused by tsunami and evacuation road to mitigate from the tsunami was studied. GIS was used as tool to predict the inundation area and evacuation route. From this research it can be shown that GIS is useful to predict the inundation area and evacuation road.
