India is having a high risk towards earthquakes. During the last 20 years, India has experienced 10 major earthquakes that have resulted in more than 35, deaths. The most vulnerable areas, essay natural disaster, according to the present seismic zone map of India include the Himalayan and Sub-Himalayan regions, Essay natural disaster and the Andaman and Essay natural disaster Islands. Though the regions of the country away from the Himalayas and other inter-plate boundaries were considered to be relatively safe from damaging earthquakes, the presence of a large number of non-engineering structures and buildings with poor foundations in these areas make these regions also susceptible to earthquakes, essay natural disaster.
In the recent past, even these areas also have experienced earthquake, essay natural disaster, of lower magnitude than the Himalayan earthquakes. The North-eastern part of the country continues to experience moderate to strong earthquakes. On an average, this region experiences an earthquake with magnitude greater than 5. The Andaman and Nicobar Islands are situated on an inter-plate boundary and therefore are likely to experience damaging earthquakes frequently. The increase in the use of high-technology equipment and tools in manufacturing and service industries have also made them susceptible to disruption due to relatively moderate ground shaking. The country receives an annual precipitation of million hectare meters. The flood hazard is compounded by the problems of sediment deposition, essay natural disaster, drainage congestion and synchronization of river floods with sea tides in the coastal plains.
The area vulnerable to floods is 40 million hectares and the average area affected by floods annually is about 8 million hectares. About 30 million essay natural disaster are affected by flood every year. Floods in the Indo-Gangetic-Brahmaputra plains are an annual feature.

On an average, five to six tropical cyclones form every year, of which essay natural disaster or three could be severe.
Cyclones occur frequently on both the Coasts the West Coast —Arabian Sea; and the East Coast —Bay of Bengal. More Cyclones occur in the Bay of Bengal than in the Arabian Sea and the ratio is approximately An analysis of the frequency of cyclones on the East and West Coasts of India between and shows that nearly cyclones occurred 92 severe in a 50 km wide strip on the East Coast. Less severe cyclonic activity has been noticed on the West Coast, with 33 cyclones occurring in the same period, out of which 19 of these were severe.
In India, Tropical cyclones occur in the months of May-June and October-November. The cyclones of severe intensity and frequency in the north Indian Ocean are bi-modal in character, with their primary peak in November and secondary peak in May. The disaster potential is particularly high at the time of landfall in the north Indian Ocean Bay of Bengal and the Arabian Sea due to the essay natural disaster destructive wind, storm surges and torrential rainfall.

In Hawaii and Japan, for example, tsunamis have been known to reach 30 m in height. At least 22 countries along the rim of the Pacific are estimated to beat risk from potential tsunami.
The fact that tsunamis can travel 10, km at velocities exceeding km per hour with little loss of energy and are, therefore, essay natural disaster, capable of hitting areas not directly affected by the inducing event, has led to the establishment of a tsunami early warning service for the whole circum-Pacific area. However, only a few of the 22 countries most at risk are considered to have standard operating procedures for immediate evacuation or reliable, rapid communication systems capable of receiving real-time warnings from the Pacific Tsunami Warning Centre. About 6,people have been killed by tsunami during alone. Probably the best documented of these events is the occurrence at Noshiro, Japan, in which caused approximately deaths and extensive property damage and flooding.

Earlier Pacific Tsunami warning system was established for forecasting the event. Judged by the frequency with which they cause damage and by the surface area of the regions they strike, windstorms can be said to be the most significant of all natural hazards. Windstorms influence precipitation systems floods and, most importantly, cause severe destruction to crops and properties. Today increasing attention is being paid to windstorms, particularly tropical cyclones as some scientists see their incidence as being a possible indicator of global climatic change and predict an increase in their frequency.
Have tropical cyclone frequencies or their intensities increased with global changes throughout the last century? However, global listings of disasters rarely include those which occur in small states such as island states, which in areas such as the Caribbean, Indian Ocean and South Pacific are particularly prone to tropical cyclones. This is because listings often set a criteria based on magnitude of impact with which small states cannot compete against larger countries. However, the proportional impact upon small states is often far greater in terms of population, housing and economics. The impact of cyclones goes far beyond just deaths and building damage.
