Many factors are responsible for the occurrence of natural disasters. Jointly, several factors may also cause a disaster or hazards. The inner and outer forces of earth directly affect some of the natural disasters. Volcanoes and earthquakes both always originate due to internal movement and forces of the earth. Man has been exploiting natural resources insensibly since the very beginning. To fulfill the demands of ever – increasing population, he has disturbed the natural form of earth.
Due to deforestation, soil and land erosion etc. we have put the atmosphere into trouble. So, man is facing the problems like global warming, flood and drought. The disasters such as landslides, cyclones, are also at large the result of mankind’s unnecessary interference in nature. Man’s consumerism viewpoint is disturbing the natural balance. All this is inviting the disasters in a direct manner.
