Seismic moment tensor inversion for earthquakes in Southeast Asia

Abstract

The method of seismic moment tensor inversion [Dreger and Langston, 1995], which uses the entire waveform recorded by a small number of stations located at regional distances from the source (100-1000 km), is applied to the Kobe and Neftegorsk earthquakes and two Korean earthquakes. The Green functions of the source-receiver paths are calibrated. The estimates of the source parameters of the main events agree well with their determinations by other methods. The mechanisms of aftershocks are similar to those of the main events.
