Intellectual Merit Our results have produced a large improvement in earthquake location accuracy for small earthquakes and dramatically sharpened seismicity features in southern California. We have also produced large catalogs of focal mechanisms and Brune-type stress drop estimates, which have facilitated large-scale analyses of the stress state of the southern California crust.
Broader Impacts We expect that catalogs and other products will be used extensively by SCEC researchers.
