2b. Earthquake catalog without duplicates for the western U.S., for use outside the UCERF3 zone (Catalog B)

In processing step 2, duplicate entries, explosions, and mining-related seismic events are deleted from wmm_wg.c1 and wmm_rw.c1. Duplicates are identified within time and distance windows, and a preference hierarchy is used to select a favorite. Non-tectonic catalogs in the literature and online event-by-type catalog searches are used to identify explosions and mining-related events. Two distinct WUS catalogs are produced in step 2 to facilitate integrating California seismicity with the rest of the WUS. The Uniform California Earthquake Rupture Forecast (UCERF3) project developed a catalog for a region extending about 100km beyond the California border. Catalog B is constructed for the whole western U.S. with the intention of using [...]
