Depending on the severity, lives can be lost in any number of disasters. Falling buildings or trees, freezing to death, being washed away, or heat stroke are just some of the deadly effects.
Some disasters cause more loss of life than others, and population density affects the death count as well. Fields saturated in salt water after tsunamis take years to grow crops again.
Homes destroyed by floods, essays on natural disasters, hurricanes, cyclones, landslides and avalanches, a volcanic eruption, or an earthquake are often beyond repair essays on natural disasters take a lot of time to become livable again.

Scientists, geologists, and storm watchers work hard to predict major disasters and avert as much damage as possible. But there arestill natural disasters that come up rather unexpectedly, such as earthquakes, wildfires, landslides, or even volcanic eruptions.

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, according to the present seismic zone map of India include the Himalayan essays on natural disasters Sub-Himalayan regions, Kutch and the Andaman and Nicobar Islands, essays on natural disasters.
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.
In the recent past, even these areas also have experienced earthquake, 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, 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 people are affected by flood every year. Floods in the Indo-Gangetic-Brahmaputra plains are an annual feature. Drought prone areas comprise About 50 million people are affected annually by drought. Of approximately 90 million hectares of rain-fed areas, about 40 million hectares are prone to scanty or no rain. Of these, the majority has their initial genesis over the Bay of Bengal and strike the east coast of India.
On an average, five to six tropical cyclones form every year, of which two essays on natural disasters 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 accompanying destructive wind, storm surges and torrential rainfall.

Mostly occurring in the Pacific Ocean, essays on natural disasters, tsunamis, although hardly noticeable at sea, can reach gigantic proportions essays on natural disasters they reach shallow, coastal waters. In Hawaii and Japan, for example, tsunamis have been known to reach 30 m in essays on natural disasters.

The fact that tsunamis can travel 10, km at velocities exceeding km per hour with little loss of energy and are, therefore, 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 essays on natural disasters. 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.

Tsunamis have multiple origin— Over past two thousand years there have been 10, 00, deaths attributed to tsunami in the Pacific region alone.
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, essays on natural disasters.
Today increasing attention is being paid to windstorms, essays on natural disasters, 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, essays on natural disasters.
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.
In developing countries destruction of infrastructure and essays on natural disasters agriculture can lead to a decrease in exports and gross national product, while increasing the likelihood of forfeiture of international loan repayments. Contamination of water supplies and destruction of crops can also lead to disease and starvation. Many mid-latitude cyclonic depressions can give rise to exceptionally heavy rain and widespread essays on natural disasters and snow fall too.
Dust storms are windstorms accompanied by suspended clay, silt materials, usually but not always without precipitation. Average million tonnes of dust are entrained by winds each year. Severe windstorms with high level of flush rain often called thunderstorms associated with lightning, hail and tornadoes cause massive destruction of properties and also human lives through out the world.
Early warning and emergency relief operation are the major management activity. Forest or bush fire, though not causing much loss to human life, is a major hazard for forest cover in the country. As per Forest Survey of India report, 50 per cent of the forest cover of the country is fire prone, out of which 6. Average annual physical loss due to forest fire in the country is estimated to worth Rs. The major loss due to forest fire is caused to the environment which gets adversely affected by this calamity.
