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).

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
