Celebrating 40 years of service!
The California Earthquake Clearinghouse is a place to coordinate earthquake field investigations and share observations and knowledge among emergency responders and the engineering and scientific communities
The California Earthquake Clearinghouse (Clearinghouse) will provide a location, real or virtual, after a damaging earthquake, where engineers, geologists, seismologists, sociologists, economists, and other professionals who arrive in the affected area can become part of a larger, temporary organization (the Clearinghouse) to facilitate the gathering of information, maximize its availability, and better use the talents of those present. These experts have a wide range of knowledge and experience, and their observations in the field can add substantially to the information available to officials managing response and recovery operations. This website provides information on the history and purpose of the Clearinghouse, the member organizations, recommendations for field investigation equipment, safety guidelines, and basic information on how to contribute to the clearinghouse after a California earthquake. Members of the Clearinghouse can also log in here. There are a number of groups on this site–click in the top right on GROUPS to see list. Three groups are standing committees of the clearinghouse: Overflight, Information Technology and Outreach. These committees welcome new participants. The other groups have been created to function in particular in an earthquake as a place where field investigators can quickly share information. Observations can be short descriptions, questions, comments. Posts will be visible to all members of the group. (To become a member, you need to register on this site.) Files will show up under Documents menu inside each group. PHOTOS, WITH BRIEF CAPTIONS, SHOULD BE UPLOADED DIRECTLY TO THE MAP. See map and instructions in tab in top right corner.
