Java island has been known to be frequently affected by earthquake. On the other side, the management of earthquake disaster mitigation is still lack of disasters anticipation and mitigation plan. It can be proven by the absence of detail damage-zonation maps of earthquake. The damage-zonation maps of earthquake are needed to assess the impact of future earthquake. Based on the 5.9 richter scale Yogyakarta earthquake on May 27, 2006, the worst affected region was around the Opak River. Therefore, the damage zonation map of earthquake in Opak River is absolutely needed to mitigate the future earthquake cases. The investigation was conducted by interviewing the earthquake witnesses scaterred in 82 locations along Opak River. The results of interview were classified based on MMI (modified mercalli intensity). By apply spatial analysis in GIS, the MMI data were interpolation and extrapolation to damage-zonation map of MMI . Reveal the result the biggest MMI classes was obtained along the Opak River and controlled by fault continuity, earthquake magnitude, distance from epicentrum, litology thickness and litology type.
