Earthquakes
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.
Floods
The most common type of flooding event typically occurs when waterways such as rivers or streams overflow their banks as a result of rainwater or a possible levee breach and cause flooding in surrounding areas.
Tsunami
Tsunamis are a series of enormous waves created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite. A tsunami can move hundreds of miles per hour in the open ocean and smash into land with waves as high as 100 feet or more.
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. Hot dry winds, high temperatures and consequent evaporation of moisture from the ground can contribute to conditions of drought.
Avalanche
An avalanche also called a snow slide or snow slip is a rapid flow of snow down a slope.
Volcanic eruptions
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. As it leaves the volcano, the lava destroys many buildings and plants it encounters.
Hailstorms
Hailstorms are falls of rain drops that arrive as ice, rather than melting before they hit the ground.
Tornado
Tornado is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and cloud.
Solar flares
A solar flare is a phenomenon where the sun suddenly releases a great amount of solar radiation, much more than normal.
