The earth beneath our feet usually feels solid and stationary.  However, on an average of once every 30 seconds around the world the ground shakes and moves under our feet.  We call this an earthquake.
    Some earthquakes are so small they go unnoticed.  Whereas other earthquakes can cause great damage and change the face of the earth.
    An earthquake is the shaking of the ground caused by the sudden release of energy in the earth's crust.  The energy is released as plates collide, slide past each other, or spread apart from each other.
