A Case Study on Tsunami Damage in India

Natural Disaster:
A natural disaster is the effect of a natural hazard that affects the environment, and leads to financial, environmental and/or human losses. Or

Any natural phenomenon that causes great damage and loss of life; The emergency situation that is the consequence of such an event.

A natural disaster is a disaster caused by nature, such as floods, volcanic eruptions, earthquakes, tsunamis, avalanches, lahars (volcanic mudslides), landslides, sinkholes, blizzards, drought, hailstorms, heat waves, hurricanes, tropical storms, typhoons, Ice Ages, tornadoes, and wildfires.

Epidemics caused by bacteria or viruses are sometimes considered natural disasters, but sometimes put into a different category. A biological threat such as locusts or toxic fungi could also be considered a natural disaster. Some disasters are on the edge of natural and non-natural.

Types Of Natural Disaster:
There are many types of Natural Disaster in this amazing world. They can be grouped as six major types. They are explained below with some examples:

1) Land Movement Disasters
i) Earthquakes
ii) Avalanches
iv)Volcanic Eruptions
2)Water Disasters
i) Floods
ii) Limnic Eruptions
3)Weather Disasters
i) Cyclonic Storms
ii) Blizzards
4)Disasters caused by Fire
i) Forest Fire
5)Health and Diseases
i) Epidemic
6)Space Disasters
i) Supernovae and Hypernovae
ii) Solar Flares
iii)Gamma Ray Bursts

1 i)Earthquakes: Sudden release of energy through the earth's crust in the form of seismic waves. Tension builds up within the crust as convectional forces in the mantle try to move the plates above but are prevented from doing so by friction between plates. When friction is overcome, an earthquake occurs. [pic]

2 i)Floods: A flood occurs when water overflows or inundates land that's normally dry. These flash floods can be extremely dangerous, instantly turning a babbling brook into a thundering wall of water and sweeping everything in its path downstream. [pic]

3 i)Cyclonic Storms: A cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth. This is usually characterized by inward spiraling winds that rotate counter clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth. [pic]

4 i)Forest Fire: A fire, often large, that consumes a forest or woodland. [pic]

5 i)Epidimic: When a disease occurs suddenly and spreads quickly through a community, with numerous people affected, and then disappears; polio epidemics occurred in the summer months.

6 i)Supernovae: A supernova (plural supernovae) is a stellar explosion that is more energetic than a nova. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. [pic]

i)Hypernovae: Hypernova (pl. hypernovae) refers to an exceptionally large star that collapses at the end of its lifespan — for example, a collapsar, or a large supernova.

Man-made Disaster:
Disastrous event caused directly and principally by one or more identifiable deliberate or negligent human actions. Also called human-made disaster. Accidental man made disasters include fire, industrial accidents, oil spills, transport disasters, and the spread of contagious diseases. Deforestation or cultivation, combined with heavy rain, leaves settlements vulnerable to landslides, soil erosion, water pollution and ultimately desertification.

1)Industrial Disaster: Industrial disasters, which are disasters caused...
