Seismic moment tensor catalog for southern Alaska

Abstract

The files here are part of the PhD thesis work by Vipul Silwal. This supplement will be cited in a manuscript to be submitted. A seismic moment tensor catalog of 106 events was generated using body waves and surface waves. The best solution (M0) was obtained through a grid-search in the double-couple moment tensor space (M) using the "cut-and-paste" (CAP) approach of Zhu and Helmberger (1996). The waveform fits for the 21 events in the Part I catalog is shown in Figure A, with the best-fitting depth plots in Figure B. The uncertainty analysis for these Part I events is shown in Figure C. The waveform fits for the other 85 events (Part II) is shown in Figure D; for these events the best depth search and uncertainty analysis was not performed.
