"Google's Android operating system have on-board accelerometers - the circuitry which detects when a phone is being moved. These are most commonly used to tell the phone to re-orientate its display from portrait to landscape mode when it is tilted, for example, and also helps provide information about step-count for Google's onboard fitness tracker."

The sensors are surprisingly sensitive, and can also act like a mini seismometer.

"Google has introduced a function that allows users to allow their phone to automatically send data to the Android Earthquake Alerts System, if their device picks up vibrations that are characteristic of the Primary waves of an earthquake. By combining data from thousands or even millions of other phones, the system can work out whether an earthquake is happening and where. It can then send out alerts to phones in the area where the seismic waves are likely to hit, giving an early warning."
