Short name | SO200-2 |
Objectives and Narrative |
To retrieve 10 OBS around SB2 deployed in June 2008 at the end of SO198-1. The OBS are part of a long-term deployment, which also includes seismometers on the forearc islands and Sumatra, recording shots from the active seismic experiment of SO198-2 and passively recording local seismic activity and teleseismic arrivals between June 2008 and February, 2009. The data will be used to help constrain large-scale velocity structure and distribution of seismicity. Wellconstrained
local earthquake locations during this deployment will also allow relocation of aftershocks from the 2004 and 2005 great earthquakes. To image the seafloor geomorphology of detailed fault structure and sediment transport features at the active prism toe using a 30 kHz deep-towed sidescan sonar system (TOBI). The seafloor structure and its variation along the margin (including across at least one segment boundary) will be correlated with existing and future MCS profiles to provide: Information on how prism thrust faults propagate from the plate boundary at depth towards the seafloor. Whether fault segmentation at the surface is comparable with segmentation at depth. Evidence for rupture of active faults to the seafloor. Evidence for how fault-related deformation affects sedimentary processes. To obtain sediment cores at strategic locations along the margin to: Determine the sedimentological record of recent great earthquakes at several locations across the prism and in the trench and at different locations along the margin. Attempt to correlate sediment layers between cores across the margin which may result from earthquake shaking. If possible, use the sediment record to assess historic earthquake frequency at different locations along the margin. |
