Evacuation route and evacuation shelter planning for tsunami hazard in Pangandaran District

The 2006 earthquake and tsunami which happened in Pangandaran caused the worst damage in the area. As we know, time and accessibility are very crucial in terms of evacuating people. There are several ways to reduce the impact of tsunami, such as evacuation direction map, evacuation route, evacuation shelter, and guide signs. The purpose of this research is to find out the potential location for the shelter evacuation and also the fastest evacuation route. Some variables used in this research are topography, accessibility, and travel time. This research also uses the GIS modeling using tools network analysis method in ArcGis to make the modeling for evacuation route and coverage area for evacuation shelter. Furthermore, this research also calculates capacity for evacuation shelter, the spatial data, the road condition, and the topography area. From the result, it can be concluded that the fastest evacuation route is slightly sloped, spacious enough, and approximately in a good condition. The location for tsunami evacuation shelter in Pangandaran is located in higher area and can be reached through the near settlement in the evacuation zone.
