Seismic Hazard Map for Papua Island

摘要

Development of seismic hazard maps for Indonesia has been conducted by experts and the results published in many science media, such as seminars and journals. However, published seismic hazard maps of Papua Island, which comprises two territories, Indonesian Papua and Papua New Guinea, are rarely found. In this paper a seismic hazard map of Papua (Papua Indonesia and Papua New Guinea) has been developed. The map was developed using probabilistic seismic hazard analysis. The analysis also used updated earthquake epicenter data up to 2016 and seismic sources studied by seismologists and geologists. The result of the complete seismic hazard analysis was a seismic hazard map of Papua with a hazard level of 10% probability of exceedance over 50 years. From the map, it can be noticed that ground motion across Papua Island is 0.06g-2.01g.
