Though a not well studied phenomenon (thankfully), it is well documented and seems to be a reliable, if brief, predictor. Even if it is only a few seconds of warning, that could mean a lot of lives saved by announced warnings or via automatic means.

the lead time is important for the value. I don't think a 3 second warning is valuable at all, but a 30 second warning might be. so we have stats on this?
3 seconds is plenty of time for a sensor to trigger an actuator to close valve, say a natural gas valve that could leak and cause fires.

Kinda like a reverse Schrodinger's Cat experiment: the cats live if the random event triggers.
