Earthquake Lists, Plots, and News: Current - Weekly - Hot

The Current Earthquakes page has lists of large earthquakes all over the world from the global network and in detail from a large variety of regional networks and maps of earthquakes in California and Hawaii. The Weekly Reports cover northern California, the US, and the world. A link to the southern California reports is also provided. The Hot News page allows us to put on somewhat more free format discussions of recent large events as compared to the automatically updated information in the current earthquakes page listed above.

Regional Studies:
San Francisco - Long Valley - Parkfield

Earthquakes and volcanoes cause deformation of the earth, deformation that can be measured with various instruments. Parkfield is the site of an ongoing earthquake prediction experiment. Long Valley was the site a a major volcanic eruption about 760,000 years ago and magmatic unrest continues there today. The San Francisco Bay area is seismically active and densely populated, a deadly combination.

Earthquake Shaking Maps:
Observed: Hanshin-Awaji (Kobe)
Predicted: S.F. Bay Area

Observed shaking maps show the distribution of strong ground motions during past earthquakes and form the basis for making predictions about what will happen during future earthquakes. The predicted shaking maps for the San Francisco Bay Area were prepared by the Association of Bay Area Governments (ABAG) and the USGS and are provided on the ABAG server.

Data Centers: Northern California - Southern California - Global - Seismosurfing

The Northern California Earthquake Data Center is shared by the U.S.G.S. and the University of California at Berkeley to archive and provide earthquake data. Public links include the ability to search the earthquake catalogs. Southern California Earthquake Center Data Center is the Southern California repository for earthquake data. The USGS National Earthquake Information Center has data covering the entire world. The Seismosurfing link takes you to a well maintained list of other sesimology resources on the net.

Miscellaneous Stuff

Here you can find out what seismologists think of earthquake risk and science, listen to a seismogram, and maybe even other stuff that has been added.

More from the U.S.G.S.

The U.S.G.S. has a lot of other information available, you can go directly to either the U.S.G.S. home page or the U.S.G.S. Earthquake page.
