Beach-balls with gray color denote historic focal mechanisms that determined by inverting BATS waveform data since July, 1995, whereas the color beach-balls indicate either the main shock or aftershocks of the 11/08/2004 15:54 event. Both gray and color scales present the corresponding centroid focal depth of each event.
