Late Quaternary Deformation of the Ambon fault, Indonesia: Preliminary Results

Abstract The Ambon fault in the northern Banda Arc has capability of generating M w 6.9 earthquake. poses a significant seismic hazard to Island because is located near populous areas, City. Recent seismicity and surrounding areas indicates that this region actively deforming. experienced many damaging earthquakes since 17 th century. However, potential on island remains enigmatic due lack detailed geological information, such as traces, slip rate, paleoseismic history. This study reports preliminary results tectonic geomorphic investigations ground-penetrating radar (GPR) surveys fault. Tectonic features, scarps, warped surfaces, sag ponds indicate late Quaternary activity predominantly shows normal sense motion with dip ~60-70°. related extensional tectonics Sea.
