Global earthquake hazard map showing the regions operating active earthquake early warning systems labeled in blue. The regions developing early warning systems are labeled in green.

Support for this project is provided by the U.S. Geological Survey. The ongoing testing of ElarmS and other early warning algorithms in California is a collaboration within the California Integrated Seismic Network (CISN) between the University of California, Berkeley, Caltech, SCEC/USC and the U.S. Geological Survey.
