You Just learnt about thunderstorm and lightning. In Class VII you learnt about cyclones. These natural phenomena can cause large scale destruction of human life and property. Fortunately, these phenomena can be predicted to some extent. The weather department can warn about a thunderstorm developing In some area. If a thunderstorm occurs there Is always a possibility of lightning and cyclones accompanying It. So. we get time to take measures to protect ourselves from the damage caused by these phenomena.There is. however, one natural phenomenon which we are not yet able to predict. It is an earthquake. It can cause damage to human life and property on a huge scale. A major earthquake occurred in India on 8th October 2005 in Uri and Tangdhar towns of North Kashmir .
