“…Despite the intense seismicity and fast motion of this fault system, it has received a little attention for active fault studies. The Matano fault in Sulawesi is a part of this large fault system and has capability of producing large earthquakes [6,7]. However, fundamental geologic information on the fault, such as fault geometry, geologic slip rate, and paleoseismic history are lacking, and this has been a barrier to understanding the neotectonics and evaluating the earthquake hazard posed by the Matano fault in Sulawesi.…”
