What is an earthquake?An earthquake is when the earth shakes, rumbles or/and rolls. It is usually when two blocks (tectonic plates) suddenly slip past each other, crash together or as two pull away from each other which is a result of tension caused by prolonged energy build up. Earthquakes come in many forms. They can be felt as a shock under your feet, or may be very powerful and destructive enough to flatten an entire city. They can happen anywhere, land or sea. Earthquakes are the vibrations caused by rocks breaking under stress. The underground surface which the rock breaks and moves is called a fault plane.
