Forecasting of Natural Calamities

India is vulnerable, in varying degrees, to a large number of hazards. More than 58.6 per cent of the landmass is prone to earthquakes of moderate to very high intensity; over 40 million hectares (12%) of its land is prone to floods and river erosion; close to 5,700 km, India's 7,516 km, long coastline is prone to cyclones and tsunamis; 68% of its cultivable area is vulnerable to droughts; and, its hilly areas are at risk from landslides and avalanches. Moreover, India is also vulnerable to chemical, biological, radiological and nuclear (CBRN) emergencies and other man-made hazards. Disaster risks in India are further compounded by increasing vulnerabilities associated with changing demographics and socio-economic conditions, unregulated urbanization, development within high-risk zones, environmental degradation, climate change, other developmental constrains, epidemics and pandemics.
