It’s interesting to see the reactions, a few seconds isn’t a lot of time but unless they can predict an Earthquake before it happens there’s no way to give people more time. Better to get a heads up than nothing, yay technology!

The underlying government system, ShakeAlert, needs to be more publicized. There have been apps for these alerts for years now, even on iPhone. It is nice that Android has the option built in though.

Yeah, nowadays it’s a lot easier to make useful technology than it is to get widespread adoption of said technology. Unfortunately being profitable is more attention-grabbing than being useful.

Participating Android phones are hooked into two different alert systems. One is ShakeAlert, but that wasn't the one that offered advance warning here. The other is that phones that have opted into the Android Earthquake Alerts System use mass collective data from their accelerometers to form a rudimentary real-time seismology dataset. The scale of the network is used to filter the seismology readings from the everyday movement noise. It's the data from that which was able to trigger the alert so rapidly and beat the shockwave, which is why this is discussing Android phones in particular.
