Earthquake Maps and Lists
We have created a number of interesting earthquake lists and maps from the ANSS catalog. These data provide a perspective on current seismicity by illustrating where events have occurred in the past. These figures were generated using Generic Mapping Tools (GMT).
Please note that, like all earthquake catalogs, the ANSS composite catalog should be used with care.
We have just added new maps showing the distribution of seismicity with depth. Enjoy!
This section is under development and we encourage comments and suggestions. Please contact anss@www.ncedc.org
The Advanced National Seismic System catalog
is hosted by the
Northern California Earthquake Data Center.
