Daftar Isi:
- Indonesia is one of the countries with a very high prone to earthquake. It has experienced several deadly earthquakes with a large number of death and property damaged. The 2006 Yogyakarta earthquake has caused highest victim from building�s damage along Opak Fault line than other places in Yogyakarta Province. It is necessary to study earthquake risk assessment in building to reduce the impact of earthquake and all of the possible hazard threat. HAZUS is a disaster risk assessment tools developed in United States. It assesses multi hazard loss estimation for the building and casualties of population. The loss estimation in HAZUS has to compare to check the validation of this result. Thus the analysis is done in adapting the application of HAZUS in Indonesia and comparing the outcome with a post disaster damage survey. Different scenario of hazard is used to estimate building damaged. The scenario of hazard is created to analyze the possibility parameter of hazard by different researcher. The scenario is based on different source of earthquake (BMG and USGS). Hazard map is based on ground motion and liquefaction potency. The data of hazard is used to generate HAZUS method in study area. Palbapang village is taken as the study area to apply the HAZUS model in Indonesian term. The study area is taken because it represents the mixture of urban and rural area and also the heavy damaged in this area as the considering factor. Unreinforced masonry is the dominant building in this area before 2006 earthquake while reinforced masonry (RM) is dominating structural type of building after 2006 earthquake. The vulnerability function is taken from HAZUS and the research by Miura in Philippine. The result from HAZUS has concluded that hazard maps have similarity with other result from previous research. The Intensity has estimated in VII- VIII MMI based on different scenario. The liquefaction susceptibility is categorized as moderate and high susceptibility which depends on lithology unit in this area. The building damaged probability of HAZUS method in scenario 1 gives more damages building in study area than in Scenario 2 and Miura. The distance from epicenter and liquefaction probability is the highest factor of hazard to create high damaged of building in study area. The correlation in building vulnerability has high relationship in URM but weak in RM and Wood. The modification is required in term of vulnerability function and complete data base to adapt HAZUS method In Indonesia.
