This document discusses disaster mitigation and management in India. It begins by defining what constitutes a disaster and provides examples of different types of natural and man-made disasters that occur in India. It then outlines the four phases of disaster management: mitigation, preparedness, response, and recovery. For each phase, it provides details on the goals and activities involved. It also discusses the role of risk assessment and developing an integrated warning and response system to help manage disasters, with a focus on tropical cyclones. Overall, the document outlines India's vulnerability to various disasters and the framework for managing disasters in the country.

Conclusion:
We cannot predict any of the disasters, but we can prevent them by mitigation and
management techniques.
So, to keep INDIA safe from all the disasters, we should have minimum knowledge about
disasters and their mitigation and management techniques.
Save greenery and Mother India from all the disasters.
