Based on Undang-undang No. 24 of 2007 about preventive of disaster, that disaster is caused by phenomenon such as earth quake, volcano eruption, flood, dryness, typhoon, and landslide. This research will analyze how to make a tsunami-prone zone map for coastal area in order to give direction to prevent tsunami disaster. This research uses image of location to create map to determine location of tsunami-prone and also evacuation path as early alarm to minimize victims. From this map, discovered that if wave height is 5 m, tsunami will reach154 m from coastline. While if wave height is 15m, tsunami will reach 488 m from coast line. If wave height is 25 m, tsunami will reach 843 m from coastline, and for wave height of 40 m, tsunami will reach 955 m from coastline.
