QCN Has Moved to the University of Southern California (USC)

After almost eight years at Stanford, and a year at CalTech, the QCN project has moved to the University of Southern California Dept. of Earth Sciences. QCN will be sponsored by the Incorporated Research Institutions for Seismology (IRIS), the Southern California Earthquake Center (SCEC), and the United States Geological Survey (USGS). Your BOINC clients should automatically connect to the new servers - if you would rather reconnect manually; you can "Remove Project" in the BOINC Manager and then "Attach Project" to our new URL: http://quakecatcher.net

Update QCN Project in BOINC

With the move to USC, we encourage you to update the project URL to ensure proper functionality going forward. In BOINC please detach from qcn.caltech.edu/sensor (or qcn.stanford.edu/sensor) and attach to project: quakecatcher.net. For detailed instructions click below.

The Quake-Catcher Network

The Quake-Catcher Network is a collaborative initiative for developing the world’s largest, low-cost strong-motion seismic network by utilizing sensors in and attached to internet-connected computers. With your help, the Quake-Catcher Network can provide better understanding of earthquakes, give early warning to schools, emergency response systems, and others. The Quake-Catcher Network also provides educational software designed to help teach about earthquakes and earthquake hazards.
