Can we recognize that an earthquake is a foreshock before the mainshock occurs?
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. How do you know if an earthquake is a foreshock? Usually, for a preceding quake to be considered a foreshock, seismologists also look for the epicenter
