Google’s Android phones started detecting earthquakes around the world. Data could give billions of users precious seconds of warning of a tremor nearby.
Android will send alerts to phones in California from the ShakeAlert earthquake early warning system.
“With the growing cost of natural disasters worldwide, we saw an opportunity to use Android to provide people with timely, helpful earthquake information when they search, as well as a few seconds warning to get themselves and their loved ones to safety if needed,” Google said in a blog post.
Accelerometers, sensors that measure direction and force of motion, are mainly used to determine whether a user is holding a phone in landscape or portrait mode.
