>often preceded

There are no guarantees in seismology, what may be "often" true is very different from "always" true. Large Earthquakes also often come without warning, and small earthquakes often don't precede anything. It's not reliable enough data for prediction and geologists (at least in Canada/States) aren't able to do much with it.

A technique seismologists do use is to examine the historical record and try to make empirical predictions from the frequency of large Earthquakes, but again this is an entirely empirical method and has very large error.

More sensors, more data, and An AI to learn it all would be an interesting possible predictor.
