Answer 1

Answer:

Nature and Management:

A natural disaster is unforeseen, severe and immediate. Pollution, ozone depletion in the stratosphere and global warming come in this category. Natural disasters include cyclones, earthquakes, floods, drought (though these two are now being increasingly considered ‘man- made’ disasters) heat and cold waves, landslides, avalanches, flash floods, severe thunder­storms, hail, low level wind shears, and microburst.The destructive potential of any natural hazard is estimated basically by its spatial extent and severity. Spatial extent upto which the effect of a disastrous event could be felt may easily be classified into small, medium and large scales. The phenomenon extending from a few kilometers to a few tens of kilometers are termed as small scale.

Management:

The management aspect of disaster may be classified as: (a) early warning system; (b) rescue operations; (c) relief operations; (d) rehabilitation; and (e) long range planning. The most important is the early warning systems. Unless sufficient advance notice is available, evacuation of the population likely to be affected cannot be undertaken.There are two aspects of early warning system. One is the availability of an effective technique to forecast the disaster with its extent and the other is effective communication of the same to the civil authority responsible for rescue operations.
