摘要

The 26 December 2004 giant Sumatra earthquake of moment magnitude 9.2 caused a large tsunami and severe damage to life and property in several coastal regions of the Indian Ocean countries1. After the 12 September 2007 thrust earthquake of magnitude 8.4 in southern Sumatra, Indonesia (epicentral location 4.517 degrees S, 101.382 degrees E; IST 16:40:26). A question arose whether this earthquake too would generate a similar tsunami as in the case of the 2004 Sumatra earthquake. This earthquake resulted from thrust faulting on the boundary between the Australia and Sunda plates. It is known that the Australian plate is moving northeast with respect to the Sunda plate, with a velocity of about 60 mm/yr. The focal mechanism shows that the direction of relative plate motion is oblique to the orientation of the plate boundary in the southern Sumatra region. This is the largest earthquake in Indonesia since the magnitude 8.6 Nias earthquake of 28 March 2005. The Nias earthquake produced a local and regional tsunami of a maximum runup height of about 5 m in the source region. No significant run-up heights were observed along the east coast of India.
