Note (4/9/2015): The ANSS Comprehensive 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.
Use the form below to search the ANSS global earthquake catalog.
Help with the
form is available. Feel free to visit the
earthquake maps and lists as well.
