Haha, initially I didn't realize it was a reference, but I remember that scene.

In theory for something like this, the earthquake alert data could be collected without anyone even reviewing it, thus this would be anonymized data and since the alert would go out quickly, a person reviewing it wouldn't necessarily be useful.

That said, it's very possible that personalized data could be reviewed later on (but much of the phone is designed to do that too- like how Amazon was able to recover deleted or unused Ring Camera video from people who were not even subscribed to it.
