Google provides Earthquake detection and early alerts on Android phones

Google said it’s part of a crowdsourced project that transforms any Android phone into a mini seismometer, joining millions of other Android phones out there to form the world’s largest earthquake detection network.  google Earthquake detection
Google collaborated with the United States Geological Survey (USGS) and California Governor’s Office of Emergency Services (Cal OES) to send earthquake alerts, powered by ShakeAlert®, directly to Android devices in California. 

Developed by the nation’s leading seismologists, the ShakeAlert 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.

Installing a ground network of seismometers, as California has done, may not be feasible in all impacted areas around the world. So Google is using the reach of Android’s platform to help detect earthquakes.

Starting today, your Android phone can be part of the Android Earthquake Alerts System, wherever you live in the world. This means your Android phone can be a mini seismometer, joining millions of other Android phones out there to form the world’s largest earthquake detection network.

All smartphones come with tiny accelerometers that can sense signals that indicate an earthquake might be happening. If the phone detects something that it thinks may be an earthquake, it sends a signal to our earthquake detection server, along with a coarse location of where the shaking occurred. The server then combines information from many phones to figure out if an earthquake is happening. Google is essentially racing the speed of light (which is roughly the speed at which signals from a phone travel) against the speed of an earthquake. Good news is, the speed of light is much faster!

To start, Google’ll use this technology to share a fast, accurate view of the impacted area on Google Search. When you look up “earthquake” or “earthquake near me,” you’ll find relevant results for your area, along with helpful resources on what to do after an earthquake.

Google worked with globally-renowned seismology and disaster experts Dr. Richard Allen, Dr. Qingkai Kong and Dr. Lucy Jones to develop this crowdsourced approach for detecting earthquakes all around the world. google Earthquake detection
