Tsunami evacuation Geographic Information System (GIS) education as disaster mitigation

Abstract

Padang City is the largest city on west coast of Sumatra and capital city of West Sumatra, Indonesia where it directly adjacent to Indian Ocean. Because of its position, the people are shadowed by fear and felt threatened when earthquake occurred. If earthquakes and tsunamis ever happened, the people need information of safe zone that in reach to evacuate their families and their own self. If someday the calamity happened, with proper education system the society will be able to anticipate the occurring events. Researcher create a Geographic Information System (GIS) with A-Star algorithm method. A-Star Algorithm using nearest distance available to reach destination and have heuristic value for consideration. In this system include alternative route, total capacity, and distance to the selected shelter. In this research, researcher using descriptive method to collect data, evacuation route, and tsunami shelter around Purus, Padang. With this system the people are expected to have sufficient information about tsunami evacuation route as means to minimalized casualties.
