Natural Disaster

A natural disaster is a terrible accident, e.g. a great flood, a big fire or an earthquake. It usually causes great suffering and loss of a large sum of money. The casualties are injured or died. Some people are homeless and need medical care.

     Floods occur when the water of rivers, lakes, or streams overflow their banks and pour out onto the surrounding land. Floods are caused by many different things. Often heavy rainstorms that last for a brief time can cause a flood. But not all heavy storms are followed by flooding. If the surrounding land is flat and can absorb the water, no flooding will occur. If, however, the land is hard and rocky, heavy rain cannot be absorbed. Where the banks are low, a river may overflow and flood adjacent lowland.

     In many parts of the world flood are caused by tropical storms called hurricanes or typhoons. They bring destructive winds of high speed, torrents of rain, and flooding. When a flood occurs, the destruction to surrounding land can be severe. Whole villages and towns are sometimes swept away by water pouring swiftly over the land. Railroad tracks blocked and are uprooted from their beds. Highways are washed away.

     When a building caught fire, the fireman pitched in to help battle the blaze. Before the pumps were invented, people formed bucket brigades to fight fires. Standings side by side, they formed a human chain from the fire to nearby well or river. They passed buckets of water from to hand to be poured on the flames.


     The damage of the fire did depend a great deal on where it happened. In the country or a small village, only a single house might burn down. But in crowded cities, fire often destroy whole blocks and neighborhoods before being controlled.
