Today, billions of Android phones in the world are not just a means of communication and internet, but they can also work like small sensors. The accelerometers installed in these smartphones can sense slight movements of the ground. When multiple phones sense the same tremor in the same area, algorithms in Google’s system combine that data to estimate the earthquake’s location, location and intensity. After this a warning is sent to the people of the affected area.
