Google has introduced an Earthquake Alert system for Android users, which sends near-instant alerts of potential earthquakes. Initially launched in 2020 on the west coast of the US, the system is now available in all 50 states and US territories.
The Earthquake Alerts utilize data from gyroscopic sensors in millions of Android phones to detect vibrations and identify earthquakes in real time. Users receive alerts if the earthquake registers above a 3 on the MMI scale, with a more intense “Take Action” alert sent for earthquakes measuring 4.5 or higher. This early warning system provides valuable seconds for individuals to seek safety during an earthquake.
In states like California, Oregon, and Washington, where earthquakes are more common, the system also integrates with the ShakeAlert system from the US Geological Survey to enhance alert capabilities.
In addition to the US mainland, the system has expanded to include territories like Alaska, Hawaii, Puerto Rico, Guam, the US Virgin Islands, American Samoa, and the Northern Mariana Islands. Google’s blog post mentions that the technology is active in 97 other countries and territories, with notable exceptions like Japan, Indonesia, and China.
