ANSS Comprehensive Earthquake Catalog (ComCat) Documentation

The ANSS Comprehensive Earthquake Catalog (ComCat) contains earthquake source parameters (e.g. hypocenters, magnitudes, phase picks and amplitudes) and other products (e.g. moment tensor solutions, macroseismic information, tectonic summaries, maps) produced by contributing seismic networks. This comprehensive collection of seismic information will eventually replace the ANSS composite catalog hosted by the Northern California Data Center; however, historic regional seismic network catalogs have not yet been fully loaded.
