SCEC Earthquake Early Warning Activities
SCEC4 science plans emphasize the development and use of time-dependent seismic hazard analysis. SCEC is working to extend time-dependent seismic hazard analysis through application of EEW technologies.
CISN ShakeAlert System
SCEC is working with the California Integrated Seismic Network (CISN) in the development and evaluation of a prototype CISN EEW system.
CISN EEW Testing System Development
SCEC is working to developed 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.
Example Observations from ShakeMap RSS for Event (M5.0 )
Authorized Data Source
The ShakeMap authorized data source may provide the observational data used to validate short term ground motion forecasts.
