Local Waveforms Analysis to Estimate the Fault Plane of May 2008 Sumatra Earthquakes

Bagus Jaya Santosa, Bintoro Anang Subagyo

Abstract


Five earthquakes source parameters in Sumatra have been estimated that occurred on May 3rd, 13th , 18-20th 2008, which earthquakes magnitude was over 5.4 Mw. To determine the earthquakes source parameters, we used three components local waveform. The seismogram data are inverted to achieve the earthquake source parameters. To investigate the depths of earthquakes, the determination used the highest value of variance reduction of waveform analysis. To identify the fault plane of the earthquakes, the H-C method is used. The research calculates also the length and width of the Fault planes.

Keywords


Three components local waveform, earthquake source parameters, earthquake depth, width and displacement
