NUMERICAL MODELING OF THE NEVELSK EARTHQUAKE AND TSUNAMI OF 2 AUGUST 2007
The anomalous tsunamigenic earthquake, which occurred on August 2, 2007 at 02.37 GMT in the Tatar Strait, near the western coast of Sakhalin Island (Nevel’sk earthquake), is examined. Though the magnitude of the main shock was M=6.2, the tsunami waves generated by this earthquake were abnormally lar...
