Earthquake Early Warning

California Integrated Seismic Network (CISN) research groups, together with SCEC and USGS, are developing a prototype CISN EEW system called the CISN ShakeAlert system. SCEC current research focus is the development of an automated CISN EEW performance evaluation system. This system, currently called the CISN Testing Center (CTC), is based on the testing framework developed on the SCEC CSEP project.

SCEC4 science plans emphasize the development and use of time-dependent seismic hazard analysis. SCEC earthquake system science research approach seeks to integrate EEW technologies into time-dependent seismic hazard analysis through applications.
