Google on Tuesday announced it is planning to roll out an earthquake alert feature for California. Android phones will receive warning notification before an earthquake strikes. And triggered by the ShakeAlert. Earthquake early-warning system implemented on the geographical region by the US Geological Survey and partners.
The ShakeAlert utilize the signal from many Seismometer installed across the state to trigger warning messages. ShakeAlert, a system that analyzes seismic data from over 700 Seismometer installed in California. Calculates preliminary magnitudes, and estimates which areas in the state will feel shaking. Since last October, Californians had access to an app called “MyShake”. Which used Wireless Emergency Alerts (WEA) to disseminate alerts powered by ShakeAlert.
California Governor Gavin Newsom says:
Google’s new system “will use the same data feed to receive and distribute alerts as the state’s Earthquake Early Warning System” used by MyShake.
The principal Software Engineer at Google Marc Stogaitis said:
“We saw a chance to use Android to provide people with timely, helpful earthquake information once they search. Also as a couple of seconds warning to urge themselves and their loved ones to safety if needed.”
People with smartphones of Android operating software were also invited to let handsets be a part of a crowd-sourced network for detecting earthquakes. Smartphones possess small accelerometers that sense movement and may catch shaking caused by the earthquake.
Marc Stogaitis also said:
“This means your Android phones are often mini Seismometer, joining many other Android phones out there to make the world’s largest earthquake detection network.”
A signal would be sent by the Android phones to the info center during the Earthquake activity, the PC at the center would quickly interpret the signals to know whether a quake is occurring or not.
