Earthquakes occur all the time all over the world, both along plate edges and along faults.
Most earthquakes occur along the edge of the oceanic and continental plates .
The plates under the oceans are called oceanic plates and the rest are continental plates. These plates are always bumping into each other, pulling away from each other, or past each other. The plates usually move at about the same speed that your fingernails grow. Earthquakes usually occur where two plates are running into each other or sliding past each other. Along Faults Earthquakes can also occur far from the edges of plates, along faults.
