Probabilistic Seismic Hazard Analysis of East Java Region, Indonesia

Adi Susilo and Zulkarnain Adnan
Abstract—Seismic hazard analysis has been conducted in the region of East Java by using the Probabilistic Seismic Hazard Analysis (PSHA). This research is used to perform seismic hazard analysis with the modeling of 3-dimensional seismic sources for return period of 500 years. PSHA analysis for East Java region performed at T = 0 second (PGA), T = 0.2 second (short period) and T = 1 seconds (long period). Model of the earthquake catalog used in this analysis is the historical earthquake from 1900 to July 2011, with the area of 5oSL – 12oSL and 105oWL - 116oWL taken from MCGA, USGS which consists of NEIC-USGS, NOAA, the PDQ and the combined catalog of the Advanced National Seismic System (ANSS), as well as the catalog of the International Seismological Center (ISC) and Engdahl, vander Hilst, and Buland (EHB) with a depth of 0-300 km and magnitude ≥ 5MW. The results showed that for the acceleration of bedrock at T = 0 second (PGA), T=0.2 seconds (short period) and T = 1 seconds (long period) have values between 0.09 g - 0.29 g, 0.19 g - 0.61 g, and 0.06 g - 0.29 g respectively. The districts having lowest and highest PGA are Sumenep and Pacitan respectively.

Index Terms—PSHA, Seismic Hazard, Peak Ground Acceleration (PGA), East Java.
