How much time does on-site early earthquake detection usually give if a population is directly above it?
I hope some of you may be able to answer, but I was wondering how much time ON-SITE early earthquake warning systems would give ahead of time before impact if the city was above the active seismic fault?
Earthquake Early Warning is a thing and is being used in countries like Mexico, Japan and Taiwan for short-term notification on earthquakes.

the problem is, there are no such systems, so guessing how they would perform is futile.

Earthquake detection is still a very new science. Part of the problem is, each earthquake is different, amd the really big ones often give little to no warning. Theres just a slow, steady building of pressure on the fault over a period of years or decades, then a sudden release of energy all at once
