How does Google’s earthquake warning system work?

according to Related post In the company, the earthquake warning function uses the capabilities of “smart” mobile phones (smartphones). All phones of this type have an accelerometer that receives a signal with every movement and tries to interpret it. When a movement indicates a seismic vibration, the mobile phone sends a signal to Google’s own server, with the characteristics of the movement but also with the “stamp”, with the coordinates where the smartphone is located.

Google’s servers combine all signals of this type that they receive from many different phones in an area to determine if this is indeed an earthquake. In this case, users receive a notification about the earthquake as it is happening.

“Essentially, we are running at the speed of light (which is the speed at which signals from a cell phone travel) versus the speed of an earthquake. Fortunately for us, the speed of light is much faster,” Google wrote.

But now, starting in California, the company has started sending notifications to Android mobile users.
