Abstract
One of the worst earthquakes occurred in Indonesia is in Bantul city, Yogyakarta province in 2006. It suffered huge amount of economic losses and many casualties. This issue become more significant, because residential buildings in Bantul city is impoverished. Moreover, Bantul city has high density of population. Here, we estimate the economic losses due to the earthquake in the future based on the vulnerability of dwellings in Bantul area using risk curve. Furthermore, we simulate a hypothetical mitigation policy of risk reduction for future earthquakes. After policy implication with various subsidy scenario, the economic losses can be reduced up to 648,017.48 USD for 0.5 % probability of exceedance in 50 years. This study indicates that the government can reduce the risk of economics significantly as the beginning in reducing risk with various factors.
