United States Geological Survey has announced an approximately $4 million in awards to Caltech, University of California Berkeley, the University of Washington and the University of Oregon, for the expansion and improvement of the ShakeAlert, an earthquake early-warning system. Division of the Humanities and Social Sciences About Overview HSS at a Glance HSS History Honors and Awards Faculty Research Awards Faculty Teaching Awards Student Prizes The Francis … ShakeA lert ® is an earthquake early warning (EEW) system that detects significant earthquakes so quickly that alerts can reach many people before shaking arrives. This relationship between SCE, Caltech and the U.S. Geological Survey dates back to 1997 when a team of scientists installed earthquake detection devices at five remote SCE substations and service centers. Existing Earthquake Early Warning (EEW) algorithms use waveform analysis for earthquake detections, estimation of source parameters (i.e., magnitude and hypocenter location), and prediction of peak ground motions at sites near the source. The early warning system, while widely praised, has received some criticism for sending unsolicited messages to phones from government watchdog groups throughout the state. The system includes geographically distributed servers, and allows for automatic fail-over if connection is lost. This relationship between SCE, Caltech and the U.S. Geological Survey dates back to 1997 when a team of scientists installed earthquake detection devices at five remote SCE substations and service centers. This new Early Earthquake Warning Project will provide seismologists several seconds of warning — and in some cases tens of seconds — that an earthquake is about to occur. Scientists and government officials celebrate milestone in West Coast's earthquake early warning system. In February of 2016 the USGS, along with its partners, rolled-out the next-generation ShakeAlert® early warning test system in California. California’s Earthquake Early Warning System Won’t Be Perfect. Skip to main content . This “production prototype” has been designed for redundant, reliable operations. This new Early Earthquake Warning Project will provide seismologists several seconds of warning — and in some cases tens of seconds — that an earthquake is about to occur. system takes 2 s, on average, to collect raw data, estimate posi-tions, and stream results. As residents of Japan, Mexico and other places that already have the alerts have learned, the system … California’s nascent earthquake early-warning system had another successful run Tuesday night when a 4.4 magnitude temblor hit the La Verne area. ShakeAlert is not earthquake prediction, rather a ShakeAlert message indicates that an earthquake has begun and shaking is imminent.

The existing earthquake early warning systems provide estimates of the location and size of earthquakes, and then ground motions at a site are estimated as a function of the epicentral distance and site soil properties. Such low latency is essential to en-abling early warning of earthquakes and tsunamis in Chile.
