Earthquake early warning (EEW) is a technology that can provide rapid information about an earthquake. Under favorable circumstances, EEW technology can provide automated warning of strong ground motions from an earthquake before those ground motions have propagated to all affected sites. EEW technology provides warnings after the earthquake has begun but before the earthquake has affected all users.

EEW Technology Description
EEW forecast capabilities require (a) ground motion (or other) geophysical sensors, (b) scientific processing software, and (c) a communication system distributing information to users. Detailed descriptions of EEW technology can be found here:
CISN EEW Project
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's current research focus on the ShakeAlert project is the development of an automated CISN EEW performance evaluation system. This EEW performance evaluation 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.
CISN and SCEC are collaborating on the development of EEW evaluation tools and techniques. Detailed EEW development notes and current evaluation results are posted on related wiki entries including:
