FORGE West Flank Coso, CA: Refined Earthquake Focal Mechanism Catalog for Southern California (1981-2010)

A refined earthquake mechanism catalog for southern Califiornia using the HASH method and locations derived from waveform cross-correlation. Each focal mechanism is obtained from grid searching for the best-fitting double-couple focal mechanism solution to both the P-wave first motion polarity records that were picked by network analysts, and the S/P amplitude ratios computed from three-component seismograms. This dataset includes around 179,000 focal mechanisms for earthquakes occurring 1981 through 2010 in southern California region. Updated datasets (through 9/30/2016) are included at the bottom of the linked page.
