  2. Earth Quake:- This is a sudden, violent shaking of the earth’s surface as a result of a great release of energy in earth crust. Earthquake causes damage to  buildings and other infrastructures.
  3. Erosion:- It refers to the washing away or removal of the earth surface (Soil) through consistent flowing of water.
  4. Flooding:- This is a situation where a large value of water settles on dry land meant  for human transportation.
