By When an earthquake begins, fast-moving P waves are detected, and emergency information can be disseminated before the arrival of slower-moving surface waves. Still, the subtle shifts of the subsurface potentially load strain on adjacent zones along a fault, which could increase the risk of a bigger temblor nearby. an earthquake ranging in magnitude from 5.5 to 6.5 on the Richter scale could occur within the next year in an area 87 miles in diameter that covers part of Los Angeles and the San Fernando and. The USGS will issue ShakeAlertMessages to facilitate the delivery of public alerts of potentially damaging earthquakes and provide warning parameter data to government agencies and private users on a region-by-region basis, as soon as the ShakeAlert system, its products, and its parametric data meet minimum quality and reliability standards in those geographic regions. Algorithms to characterize the earthquake source must process large volumes of data in real-time to determine when and where an alert should be issued. This enables the USGS and ANSS to leverage their substantial investment in sensor networks, data telemetry systems, data processing centers, and software for earthquake monitoring activities residing in these network centers.
