A GIS-Based Approach to the Selection of Evacuation Shelter Buildings and Routes for Tsunami Risk Reduction: A Case Study of Cilacap Coastal Area, Indonesia

---

Cilacap is the only coastal city which is located in the southern part of Java Island which has been hit by tsunami on July 17, 2006. The region occupies a flat area and has become one of industrial center supported by many international sea ports, fish markets and many tourist destinations. Besides occupying low-lying areas near the coast, Cilacap lies in tsunami hazard zones and it is always possible to be struck by tsunami again. This research tried to develop a method to choose the most effective evacuation routes using GIS tools in a tsunami-prone area, case of Cilacap coastal area. Network analyst and many GI techniques were used to determine the location and capacity of potential suitable evacuation shelter buildings and also the most effective evacuation route for tsunami. Since ArcGIS Network Analyst software incorporates an advanced connectivity model to accurately characterize realworld multimodal networks. The evacuation process was simulated that the residents of the inundation area will be encouraged to walk to safe areas in certain of time. The results of the modeling include proposed location of additional ESBs, capacity and service area of each building, and also evacuation route for each center of population to reach escape buildings. The number of additional shelters should be added were different for the different characteristic of study areas regarding the number of evacuees. Daytime and night-time scenarios were also resulted in the different distribution and number of shelters needed. The effective evacuation routes were developed for each service area. Travel time was an essential factor to be considered since it would limit the movement of evacuees in evacuation process
