Abstract
The Sumatra Island, which is close to the active subduction zone between the Indo-Australian and Eurasian plates, experienced numerous earthquakes in the historical past. One of those earthquakes is the 2004 Mw 9.1 off-Sumatra earthquake, considered to be the second largest event ever recorded in history after the 1960’s Chilean earthquake (Mw 9.5). To analyze the impact of 2004 Sumatra earthquake in the background stress field along the Sunda margin, we retrieve the principal stress orientations of background seismic activities based on focal mechanisms’ solutions. Co-seismic slip data were also being used to compute the static stress changes in the study area. We found a significant counterclockwise rotation of maximum compressive stress axis of around 25° following the 2004 event. This perturbation corresponds to a moderate difference between the mainshock and the background principal stress orientations. This result indicates that the 2004 event caused a redistribution of stress field around the Sunda subduction margin.
