The phenomenon extending from a few kilometers to a few tens of kilometers are termed as small scale. Growing industrialisation and unjustified exploitation of natural resources have brought our echo system to a verge of non-reversibility and imbalance.

This has led to a threat from a set of natural hazards like pollution, global warming and ozone depletion on large or global scale. The management aspect of disaster may be classified as: The most important is the early warning systems.

On the contrary, in earthquakes no proven methods has yet been evolved to give any prior warning and so post-hazard mitigation is the only alternative.

The theory of plate tectonics offers a comprehensive explanation for several geological phenomena — continental drift, mountain building and volcanism, and, of course, earthquake. According to this theory, when the molten mass that was the earth billions of years ago cooled down, the crust that was formed was not one homogenous piece but broken into about a dozen large plates and several smaller ones with their thickness ranging from 30 km down to the lithosphere at depth of about km or so.

The plates are in incessant motion, with speeds of about 1 cm to 5 cm a year. Where two places converge or collide, a deep trench forms and one plate is deflected downwards into the asthenosphere which lies below the crust and the lithosphere.Cause & Effect Essay: Natural Disasters and Their Causes Natural disasters happen all over the world, and they can be utterly devastating for people’s lives and the environments in which they live.
