Rising population and development pressures, particularly from logging and tourism, cause deforestation. The result is denuded hillsides which exacerbate the severity of landslides; since tree cover impedes the downhill flow of water.
Avalanches occurrences are common in Kashmir, Himachal Pradesh, and Sikkim. Floods in India Floods are the most common natural disaster in India. The heavy southwest monsoon rains cause the Brahmaputra and other rivers to distend their banks, often flooding surrounding areas. Though they provide rice paddy farmers with a largely dependable source of natural irrigation and fertilisation, the floods can kill thousands and displace millions.

Excess, erratic, or untimely monsoon rainfall may also wash away or otherwise ruin crops. Almost all of India is flood-prone, and extreme precipitation events, such as flash floods and torrential rains, have become increasingly common in central India sisasters the past several decades, coinciding with rising temperatures. Meanwhile, the annual precipitation totals have shown a gradual decline, due to a weakening monsoon circulation as a result of the rapid warming in the Indian Ocean and a reduced land-sea temperature difference.
This means that there are more extreme rainfall events intermittent with longer dry spells over central India in the recent decades. Cyclones in India Intertropical Convergence Zone, may affect thousands of Indians living in the coastal regions. Tropical cyclogenesis is particularly common in the northern reaches of the Indian Ocean in and around the Bay of Bengal. Cyclones bring with them heavy rains, storm surges, and winds that often cut affected areas off from relief and supplies.
Presently, in India, it is estimated that around 10 lakhs buildings which are constructed every year, an equal number of them get damaged as a result of disasters. The sensors will be linked to the satellite that will relay information to the earth station. Disaster management calls for collective and co-ordinated efforts. Atmospheric science, for example, is not yet in a position to unambiguously predict the motion and behaviour of a cyclone more than 24 hours ahead of its arrival. Experience has shown that it remains completely unaffected under the severest cyclonic condition.
In the North Indian Ocean Basin, the cyclone season runs from April to December, with peak activity between May and November. Each year, an average of eight storms with sustained wind speeds greater than 63 cisasters per hour 39 mph form; of these, two strengthen into true tropical cyclones, which have sustained gusts natutal than kilometres per hour 73 mph.
On average, a major Category 3 or higher cyclone develops every other year. During summer, the Bay of Bengal is subject to disastefs heating, giving rise to humid and unstable air masses that produce cyclones.
This is far more likely to happen when there is a great deal of heavy rain, so during very wet periods, flood warnings are often put in place. Waves that move the fastest are called primary, or P, waves. There are two aspects of early warning system. Furthermore, because the intensity of shaking varies from one place to another during an earthquake, different Mercalli ratings link be given for the same earthquake. What made the earthquake more tragic was that many parts of the state were reeling under a drought for the second successive year. The most intense earthquakes occur on the boundaries of the Indian plate to the east, north and west. One of the worst natural disasters in the history of India, the cyclone struck the tiny city Coringa in Godavari district in Andhra Pradesh. We bring the 10 most dangerous natural disasters occurring in the history of India over the years:
Many powerful cyclones, including the Calcutta cyclone, the Bhola cyclone, the Bangladesh cyclone and the Odisha cyclone have led to widespread devastation along parts of the eastern coast of India and neighboring Bangladesh. Widespread death and property destruction are reported every year in esasy coastal states such as Andhra Pradesh, Orissa, Tamil Nadu, and West Bengal.
India's western coast, bordering the more placid Arabian Sea, experiences cyclones only rarely; these mainly strike Gujarat and, less frequently, Kerala. Cyclones in India[ edit ] Intertropical Convergence Zonemay affect thousands of Indians living in the coastal regions.
Natural disasters have been taking toll on various parts of the world, since then. But, in a few cases like flash floods, microburst, etc. It cannot avert the situation, but can mitigate its impacts. The extent of damage also depends on how populated and developed an area is. A circle of appropriate radius is drawn around each station.

In terms of damage and loss of life, Cyclone 05Ba supercyclone that struck Orissa on 29 Octoberwas the worst in more than a quarter-century.
