Dec. 9, 2001: The USGS Web sites are back! Please see this site for more information on the service lapse.
On Thursday, Dec. 6, 2001, the USGS was ordered to disconnect all external Internet connections by the Office of the Secretary of the Interior. The order includes email as well as popular Web pages.
Because earthquake reporting is a collaborative effort by the CISN members, earthquake information for California continues to be available to emergency responders and the public.
Real-time earthquake information is available at these alternate Web sites:
The "Did you feel it?" Web pages are unavailable at this time.
Access to the Northern and Southern California Earthquake Data Centers and the Engineering Strong-Motion Data Center is unaffected.
