 Abstract: An integrated geological and geophysical approach was applied to comprehend the tectonic setting and seismic structure of the North Tapanuli district (North Sumatra Indonesia) where several geothermal manifestations are located. For the first time, passive seismic methods are used as a geothermal exploration tool in Indonesia. The specific aims of the seismological study are to provide Vp, Vp/Vs, and seismic attenuation images as well as the detailed fault structure of the region derived from seismicity and focal mechanism analysis. A seismic network of 42 short period instruments was installed in the region covering the Tarutung (in the north) and the Sarulla basin (in the south) for 10 months starting from May 2011. The seismic arrivals were detected by using an optimized automatic earthquake detection approach. The earthquakes were then localized by using HYPO71 with a 1D velocity model. In order to increase the picking accuracy, the seismic onsets were revised manually and the earthquakes were relocated by using the same procedure.
