Abstract

Tasikmalaya, as the capital city of Tasikmalaya Prefecture in West Java Province, Indonesia, which has a high density population. More than 600.000 peoples are living in this city, many buildings, and some important infrastructures has been built. Base on probabilistic seismic hazard map of Indonesia by National Standardization Agency, shown the Tasikmalaya City located at the region of Peak Ground Acceleration (PGA)= 0.4 – 0.5 g and Pseudo Spectral Acceleration (PSA S_S: 0.2 second and PSA S₁: 1 second= 0.7 – 0.8g and 0.4 – 0.5g, for Soil Class SB, 2% probability in 50 years. In order to mitigate seismic risk, a potential seismic hazard micro-zonation map has been produced as guidance for urban city planning. We classify three potential seismic hazard micro-zonation based on the wave velocity of Vs30. The first class is High Potential Seismic Hazard Zones (Vs30 < 175 m/second and amplification 2), the second is Medium Potential Seismic Hazard Zonation (Vs30= 175 – 350 m/second and amplification 1.5), and the third is Low Potential Seismic Hazard Zonation (Vs30 = 350 – 750 m/second and amplification 1). The assessment of potential seismic hazard and risk refer to National Standardization Agency, the building and non-building has the risk categories I, II, III, and IV which are located in High, Medium and Low Potential Seismic Hazard Zonation’s. The risk category recommend to have building and non-building structures with seismic design categories D. However, the building and non-building that have been built do not follow the seismic design particularly design category D. Therefore, potential seismic risk and seismic design categories are recommended to be applied to spatial planning as an effort to mitigate earthquake risk in the city of Tasikmalaya. We defined 9 active faults and 5 potential active faults surrounding in the city. Most of them are threaten the settlement with a variety of maximum credible earthquake.
