    What is an earthquake?

   An earthquake is caused by a sudden slip on
    the fault.
   The slip happens when the stresses in the
    earth’s outer layer push
    the side of the fault together.
   The slip produces energy, and
     shakes the ground.
Under the earth’s surface
How it happens?
 Kinds of earthquakes

There are two kinds of earthquakes.

1. The earthquake which happens in the sea.
2. The earthquake which happens in the
The earthquake which happens in the sea

 The plate under the sea is forced further

      The earthquake which happens
                in the sea

The warp becomes
  bigger and bigger,
  and finally the plate
  above tries to return
  to its original
  position. This
  movement is an
        The earthquake which happens
                 in the ground

The cause is the same as the earthquake in the sea.
The warp makes energy. It shifts the ground and
breaks the plate. This is called a fault.
               Four kinds of faults
