Earthquake Maps and Lists
Note (4/9/2015): The ANSS Comprehensive Catalog (ComCat), a newer and different ANSS catalog, 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 into the ANSS Comprehensive Catalog.
We are hoping to update the selection of earthquake maps and lists from the ANSS Composite catalog.
- Special Maps
- Maps of earthquakes
- This page contains earthquake maps for various regions of the world and the United States, generated from the ANSS Composite Catalog. These maps include earthquake through mid 1997.
- Earthquake depths
- This page illustrates the distribution of earthquakes with depth and includes several cross-section plots.
- Monthly maps of global earthquake activity
- These maps are generated by the Berkeley Seismological Laboratory on a monthly basis using data from the ANSS Composite Catalog.
The ANSS Composite Catalog can be used as part of a middle school science lesson of earthquakes. Here is an example:
