Natural calamity is a natural event which has an adverse socio-economic impact on the whole environment. Natural disasters are very common in Bangladesh due to her peculiar geography. In recent years, they are becoming more destructive. Every year some common natural disasters like floods, cyclones, tidal-bores, excessive rainfall, earthquake, riverbank erosion, drought etc. visit Bangladesh. Another furious natural disaster, greenhouse effect is creeping towards us. Natural disaster causes heavy losses in our country. Many people are killed and many other become homeless. The havoc also includes death of cattle, widespread destruction of houses uprooting of trees, damage of crops, roads and structures. Shortly after the disaster, many diseases break out and communication system becomes out of order causing untold sufferings to people. However, being a natural phenomenon, it is not possible to prevent these disasters. We can take some protective measures to lessen the sufferings of the victims. Warning and preparedness measures have to be improved and finally we should raise awareness in people to protect our lives and properties from the tremendous attack of natural calamities.
