Earth quake waves

                                      Earth quake waves   


  •     Sliding of tectonic plats that occur naturally in interior of the earth cause earthquakes.Earthquakes are caused by the sudden release of built up stress along faults or cracks in the earth  
  •     When the plates of the sea bed (tectonic plates)come into contact with each     other.a sudden release of energy comes up as earth quakes 




  • The shocks waves from this sudden movement comes to the surface as an earth quake
                                                     The place where an earthquake is formed is called the epicenter
