Disaster Management: India’s Vulnerability and Hazard Profile Indian sub-continent has unique geo-climatic and socio-political conditions that make it vulnerable to both the natural as well as manmade disasters.  Around 6% of the population of India is impacted annually by the exposures to disasters. They Key natural disasters in India include floods, droughts, cyclones, earthquakes, landslides and avalanches that have resulted in loss of lives and livelihoods. According to a Planning Commission report, the key vulnerabilities of India include the following: ·          Coastal States, particularly in the East Coast and Gujarat on west coast, are vulnerable to cyclones. ·          4 crore hectare land mass is vulnerable to floods and river erosion. ·          68 per cent of net sown area is vulnerable to drought. ·          55 per cent of total area is in Seismic Zones III-V and vulnerable to earthquakes of moderate to high density. ·          Sub-Himalayan/ Western
