With distributed ray detectors and suitable modeling of inner earth processes, assuming that the premise is correct - seems it may have potential to work?

Ie, maybe able to generate the level of specificity required.

EDIT: Also there aren't that many places on earth at high risk of earthquake that also have poor construction, etc. Meaning any advance warning, that a significant quake may hit somewhere, can trigger "battening down the hatches".

You'd have to get a theory of why the rays correlate to earthquakes to have a usable model.

Realistically, if you live in a place with poor construction and relatively large earthquake risk, the sensible thing is to always have your emergency kit ready to go. Chances are, you have other infrastructure issues anyway, so keeping a week or so of emergency rations and water available might come in handy more often than somewhere that has tigher building codes (and enforcement). It would likely be hard for everyone to prep within the same two week window anyway. But, if it was quite specific and accurate, relief organizations could begin staging and start traveling to be closer and quicker to respond.

Doesn't seem like it's anywhere close to that from descriptions in this thread.
