Purpose | |
Abstract | Cruise 198-2 formed a coherent set of geophysical observations in the source regions of the 2004 and 2005 great Sumatra earthquakes. A sound-velocity correction was applied based on the velocity profile acquired during SO198-1 from XBT sequence extended in depth to account for the deep velocity structure, depending on location relative to the trench. No other acquisition information have been provided. |
