That's an interesting case because there were a couple of big foreshocks several months beforehand, and there was the odd recording made by Tony Frasier-Smith in hours and minutes beforehand of EM signals.

In addition, KB had a prediction out (albeit over a very large area), Al Lindh said he had a bad feeling after the foreshocks, and the area was given a high probability over a several decade time-scale by a blue-ribbon team of scientists.

Most of us would guess even today that even a targeted deployment of instruments would not have shown any further precursor seismicity or precursory deformation, and have shown that Tony's signal was an instrumental problem, but of course we'll never know now.

It's the 20-20 hindsight problem. Good luck with Pepe. A blast of pepper spray sounds like just the thing.
