Tsunami Generation from the 2004 M=9.2 Sumatra-Andaman Earthquake
The December 26, 2004 magnitude (M) 9.2 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. The pages on this web site listed in the Table of Contents above provide a brief overview of the tectonic setting and seismological chacteristics of the earthquake, as well as a summary of tsunami generation modeling for this event and the March 28, 2005 M=8.6 northern Sumatra earthquake. For additional information, the Disaster Prevention Research Institute at Kyoto University provides a comprehensive web site of data collected in the aftermath of this event.
