| Over the last 20 years, the Great Sumatran Fault (GSF) has been studied on land, but we have very little information about its offshore extension NW of Sumatra and its link with the West Andaman Fault to the north. The problem is further complicated by its vicinity to the volcanic arc. Here we present detailed analyses of the offshore extension of the GSF based on recently acquired high-resolution bathymetry, multichannel seismic reflection data and some old single channel seismic reflection data. Our findings demonstrate that the branches of the GSF near Banda Aceh proceed further northwestward producing two 15-20 km wide adjacent basins. The southwestern transpressional Breueh basin is 1-2 km deep and has a flower structure with a push-up ridge in the... |
