A good prediction must indicate when and where an earthquake will take place. Fault segments behave the same way over time. Signs that an earthquakes may occur include foreshocks, ground tilting, water levels in wells, and
the relative arrival times of P- and S-waves
.

Every time a small earthquake happens, doesn’t mean there is going to be a larger one
