The California Earthquake Clearinghouse has been activated in response, and all clearinghouse partners extend our sympathy to those affected as the rescue and relief work continues.

The Earthquake Engineering Research Institute (EERI), one of the Clearinghouse managing partners, has established a virtual earthquake clearinghouse website here for sharing reconnaissance data and observations as they emerge. At this time, the activation is virtual only and no physical clearinghouse has been established.
