The 2016 M6.5 Pidie Jaya Earthquake, Aceh Province, Indonesia occur in the morning at 05. 03.36 local time. The epicenter was first automatically estimated by BMKG inland at 5,19 N and 96,36 E, then updated offshore 5,25 N dan 96,24 E, in the depth of 15 Km. The shaking was widely felt across Aceh Province, with intensity VII-VIII MMI, causing 106 casualties, 700 injuries, and 16.238 house damages (BNPB, 2017). This earthquake occurred in place where no fault is mapped in the 2010 National Seismic Hazard Map of Indonesia. The National Center for Earthquake Studies then conducted survey to mapped the source fault of the earthquake. We conducted field observation of surface ruptures and deploy temporary continuous GPS measurement 3 days after the main shock. We analyze the fault location based on field observation data, seismicity data, geomorphology data, and geodetic INSAR data. We present the preliminary result of the fault source of the 2016 Pidie Jaya earthquake based on those data, which is updated in the New National Seismic Hazard Map 2016.
