What is the CISN?
• The California Integrated Seismic Network is a collaborative effort to integrate existing, separate California earthquake monitoring networks into a single seismic monitoring system.
• The CISN provides the organizational framework to coordinate these earthquake-monitoring operations.
• The CISN constitutes the California region within Advanced National Seismic System (ANSS).
Who is the CISN?
• Core members have primary responsibility for the recording and monitoring of earthquakes and the creation of CISN products – California Geological Survey– U.C. Berkeley Seismological Laboratory– Caltech Seismological Laboratory– Menlo Park USGS– Pasadena USGS– USGS National Strong Motion Program

Participating members contribute to CISN activities through data exchange.
CISN Goals
• Operate a reliable and robust statewide system to record earthquake ground motions over the relevant range of frequencies and shaking levels
• Distribute information about earthquakes rapidly after their occurrence for emergency response and public information
• Create an easily accessible archive of California earthquake data for engineering and seismological research, including waveform data and derived products
