READINESS ANALYSIS OF PUBLIC BUILDINGS IN PADANG CITY FOR TSUNAMI TEMPORARY EVACUATION SHELTER

Abstract

The potential mega-earthquake at Mentawai Megathrust could trigger a deadly tsunami. The tsunami can reach Padang City within 20-30 minutes. Thus, people in Padang City need to be evacuated immediately either to the higher ground or to the high-rise buildings located in Padang City. Reaching higher ground is not easy as it takes time and is hampered by traffic. Therefore, vertical evacuation to high-rise buildings is very important to be studied. This paper aims to identify, analyze and measure the readiness of the potential buildings to be used as temporary evacuation shelters for tsunami disaster evacuation. The research was conducted using observation of twenty-three potential buildings and interviews. The readiness of the buildings is assessed using 23 criteria, which were divided into 6 main criteria and 17 supporting criteria. It was found that none of the buildings was ready as a tsunami evacuation shelter. To be ready as a tsunami evacuation shelter, seven buildings that meet all six main criteria need to improve their supporting facilities and infrastructure, while the other 16 buildings have to be improved to meet all the main and supporting criteria.
