How Android Earthquake Alerts System Works on Android?

Earthquakes happen daily around the world, with hundreds of millions of people living in earthquake prone regions. An early warning can help people prepare for shaking, but the public infrastructure to detect and alert everyone for an earthquake is costly to build and deploy. It is an opportunity to use Android to provide people with timely, helpful earthquake information when they use Google search, and a few seconds warning to get themselves and their loved ones to safety if needed.

Android Earthquake Alerts System is a free service that detects earthquakes around the world and can alert Android users before shaking starts.

Developed by the nation’s leading seismologists, the Shake Alert system uses signals from more than 700 seismometers installed across the state by USGS, Cal OES, University of California Berkeley, and the California Institute of Technology. A few seconds of warning can make a difference in giving you time to drop, cover, and hold on before the shaking arrives.
