What causes an earthquake ?

Earthquakes are usually caused when rock underground suddenly breaks along a fault. ... When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving.
