Source Parameters of Regional Earthquakes in Taiwan: January-December, 1997

Abstract

Establishment of the "Broadband Array in Taiwan for Seismology (BATS)" has enabled the systematic determination of reliable source parameters for regional earthquakes in Taiwan through waveform inversion technique. Using an improved algorithm by Kao et al. (1998) to overcome the generally higher background noise as well as the heterogeneous velocity structure resulted from the complex tectonic interactions near Taiwan, we report source parameters of 46 events that occurred in 1997. The infersion quality is classified by a combination of a letter (A-F) and a digit (1-4) reflecting the waveform misfit and the compensated linear vector dipole (CLVD) component, respectively. To make the results more accessible and useful to the academic community, both the table that summarizes the reported source parameters and the complete set of inversion results are available electronically from the BATS web site at http://bats.earth.sinica.edu.tw/CMT_Solutions/cmtF1997.html.
