Following the instant alert last night about the earthquake in Melbourne, it's fascinating to read this article from 2020 about how the Android Earthquake Alerts System works.

Earthquake detection and early alerts, now on your Android phone

"Your Android phone can be part of the Android Earthquake Alerts System, wherever you live in the world. This means your Android phone can be a mini seismometer, joining millions of other Android phones out there to form the world’s largest earthquake detection network.
All smartphones come with tiny accelerometers that can sense signals that indicate an earthquake might be happening. If the phone detects something that it thinks may be an earthquake, it sends a signal to our earthquake detection server, along with a coarse location of where the shaking occurred."
