Tsunami Generation from the 2004 M=9.1 Sumatra-Andaman Earthquake

The December 26, 2004 magnitude (M) 9.1 Sumatra-Andaman earthquake occurred along a tectonic subduction zone in which the India Plate, an oceanic plate, is being subducted beneath the Burma micro-plate, part of the larger Sunda plate. The boundary between the downgoing and overriding plates of the subduction zone is marked by the Sunda Trench above. Here we provide a brief overview of the tectonic...
