Do earthquakes have foreshocks?
GeologyForeshocks are earthquakes that precede larger earthquakes in the same location. An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs. Do all major earthquakes have foreshocks? This means that there is about a 94% chance that any earthquake will NOT be a foreshock. In California, about
