[1] ElarmS is a network-based methodology for rapid
earthquake detection, location and hazard assessment in the
form of magnitude estimation and peak ground motion
prediction. The methodology is currently being tested as
part of the real-time seismic system in California
leveraging the resources of the California Integrated
Seismic Network (CISN) and the Advanced National
Seismic System. A total of 603 velocity and acceleration
sensors at 383 sites across the state stream waveform data
to ElarmS processing modules at three network processing
centers where waveforms are reduced to a few parameters.
