Your phone predicts an earthquake

Google's Android operating system now has a feature that can warn users about impending earthquakes before the shaking starts. This is made possible by using the accelerometers in Android devices to detect the initial seismic waves of an earthquake, which travel faster than the destructive shaking that follows. When the system detects these initial waves, it can send out a warning to nearby Android users, giving them precious seconds to take cover. Similar earthquake early warning features are also available for iPhone users, though they may require downloading a dedicated app. These systems leverage a network of sensors to detect earthquakes and relay warnings to users' devices. While the warnings may only provide a few seconds of advance notice, that can still be enough time for people to protect themselves and minimize potential damage. This technology represents an important advancement in earthquake preparedness, providing individuals with a crucial heads-up before the shaking begins.
