EARTHQUAKE:







     •What is an Earthquake?



      An earthquake is the shaking of the surface of


          Earth due to the sudden release of energy in



          the Earth’s crust, as a result, seismic


          waves (also known as S waves)are created.




      The seismic activities in an area determine the


          type and intensity of the earthquake.
