Summary
|
Abstract:
A magnitude 9.0 megathrust earthquake occurred on December 26, 2004 just off the coast of Sumatra, Indonesia. The earthquake happened on the interface of the India and Burma plates. Based on preliminary locations of larger aftershocks, approximately 1200 kilometers of the plate boundary slipped as a result of the earthquake. From the size of the earthquake it is likely that average displacement on the fault plane was about 15 meters. Images shown are of seismometer recordings, taken by IRIS GSN stations, of ground motion during the Sumatran earthquake. There is a plot that shows the accelerations observed at 3 different IRIS/IDA stations. "http://www.iris.iris.edu/sumatra/" |
