Abstract
Southern coast of Java Island is one of the areas that susceptible of Tsunami wave impact. Pacitan city topography which located around bay area makes it become one of the city with high risk of water influx if Tsunami happen. Thus, Shelter evacuation is necessary to protect citizens from the impact of Tsunami wave.To minimalize number of victims, government has determined ‘the safety zone’ as a temporary shelter if Tsunami happens. However it is located outside Tsunami coverage area according to the map that published by Mardiatno (2008). After evacuation drill is performed at existing shelter, it has been identified that majority of residents did not have enough time to reach the nearest shelter point (using various scenarios and different timeframe). There are only 22.93% - 71.28% of residents that successfully reached the shelter.Ineffective evaluation result will possibly increase the number of Tsunami victims. Therefore, it is recommended that the nearby area should have at least 45 shelters (public places or mosques) and located within the submergence area, thus, required time for evacuation is lesser. With the support of ArcGIS software, shelter is analyzed by building service area for each shelter based on the required time to perform evacuation and maximum distance. After implementation, number of residents that have enough time to reach evacuation point is increased to 80.22% - 83.09%. In conclusion, recommended shelter is more effective than the existing shelter in Pacitan area.
