Products:
The CISN provides reliable monitoring and continuous reporting of all significant earthquake activity in California. The CISN distributes notification of earthquakes electronically through the Web and through other means.
CISN Projects: Earthquake Early Warning
For more than 10 years, people in Japan have received an alert when a big earthquake has started and they will imminently experience strong shaking. A similar "Earthquake Early Warning" system, called ShakeAlert, is now in prototype testing in California, using CISN infrastructure, and the Pacific Northwest. With political will, scientific effort and investment in infrastructure, alerts are now publicly available in California and will soon be available to all US West Coast residents.
