Ziel der Reise / Objectives of Cruise:

Destructive subduction zone earthquakes, like the Mw=8.8 27. February 2010 Chile earthquake, are caused by sudden slippage of the subduction megathrust fault. Once nucleation occurs locally, rupture can propagate and expand in an earthquake. However, rupture generally stops several tens of kilometers landward of the trench axis below the marine fore-arc at the so called updip limit of co-seismic rupture. The location of the seaward updip limit is critical for defining the size of a tsunami generated by the earthquake. Aftershocks can be used defining the location of the updip limit. However, events reported in global catalogues have generally large uncertainties in the order of several tens of kilometres. During the cruise we deployed a dense network of ocean bottom seismometers data that will record for three month the aftershock sequence of the Great Mw=8.8 Chile earthquake of February 2010. Data will be used to define the geographical location and nature of the processes controlling the updip limit and slip distribution. The research vessel SONNE left Coquimbo on September 17, 2010 at 01:00 p.m. local time and sailed toward the sout heading for the rupture area of the Great Maule earthquake of 2010. R/V SONNE reached the first deployment location on September 18, 2010 at 12:20 and deployed the frist ocean bottom seismometer. Every 2 hours an OBS was deployed. The last OBS #30 was deployed on September 20 at 19:10 local time. SONNE sailed northward and met the pilot off Valparaiso on Setember 21, 2010 at 8:00 local time.
