Synthetic seismograms at regional distances for May 1995 earthquake and explosion sources in Western China

PDF Version Also Available for Download.

Description

Waveforms recorded at several regional seismic stations at varying azimuths form explosion and earthquake sources in western China exhibit marked variation from station to station. We have performed two-dimensional finite difference simulations of these events, using moment tensor sources and simple crustal structure models, to generate synthetic seismograms at these locations. The synthetic seismograms at three locations exhibit behavior that is qualitatively consistent with the data, while computational results at a fourth station differ from the data. We discuss these results, the assumptions of the simulations, and the limitations of this type of modeling in the context of regional seismic ... continued below
