NATURAL DISASTER:
A natural disaster is a major adverse event resulting from natural processes of the Earth. A natural disaster can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover.

TYPES OF NATURAL DISASTERS:

1-EARTHQUAKES:
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes manifest themselves by vibration, shaking and sometimes displacement of the ground.

2-VOLCANIC ERUPTIONS:
The effects include the volcanic eruption itself that may cause harm following the explosion of the volcano or the fall of rock. Second, lava may be produced during the eruption of a volcano.. Third, volcanic ash  may form a cloud, and settle thickly in nearby locations.

3-FLOODS:
A flood is an overflow of an expanse of water that submerges land. It causes great damage to buildings, wildlife and humans.

4-LIMNIC ERUPTIONS:
A limnic eruption occurs when a gas, usually CO2, suddenly erupts from deep lake water, posing the threat of suffocating wildlife, livestock and humans. Such an eruption may also cause tsunamis in the lake as the rising gas displaces water.

5-TSUNAMI:
Tsunamis can be caused by undersea earthquake.

6-BLIZZARD:
Blizzards are severe winter storms characterized by heavy snow and strong winds.

7-CYCLONIC STORMS:
Cyclone, tropical cyclone, hurricane, and typhoon are different names for the same phenomenon a cyclonic storm system that forms over the oceans.

8-DROUGHTS:
Drought is unusual dryness of soil, resulting in crop failure and shortage of water for other uses, caused by significantly lower rainfall than average over a prolonged period

9-HAILSTORMS:
Hailstorms are falls of rain drops that arrive as ice, rather than melting before they hit the ground.

10-HEATWAVES:
A heat wave is a period of unusually and excessively hot weather.

11-TORNADO-
A tornado is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is also referred to as a twister or a cyclone

MAN MADE DISASTERS:

TYPES:
Arson

Arson is the criminal intent of setting a fire with intent to cause damage.

Terrorism

One definition means a violent action targeting civilians exclusively. It causes great damage to human life and economic conditions as well.

Industrial Hazards

Industrial disasters occur in a commercial context, such as mining disasters. They often have an environmental impact.

Structural Collapse

Structural collapses are often caused by engineering failures. Many people die during stru…
