Tornado

A tornado is a violently 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. They are often referred to as twisters or cyclones, although the word cyclone is used in meteorology, in a wider sense, to name any closed low pressure circulation.

Tsunami

Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide, and for this reason they are often referred to as tidal waves. Tsunamis generally consist of a series of waves with periods ranging from minutes to hours, arriving in a so-called "wave train".

Earth quake

An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

Bush Fire

Bush fires in Australia are frequently occurring events during the hotter months of the year due to Australia's mostly hot, dry climate. Large areas of land are ravaged every year by bush fires, which also cause property damage and loss of life.

Eruption

During a volcanic eruption, lava, tephra (ash, lapilli, volcanic bombs and blocks), and various gases are expelled from a volcanic vent or fissure. Several types of volcanic eruptions have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series.

Avalanche

An avalanche (also called a snow slide or snow slip) is a rapid flow of snow down a slope. Avalanches are typically triggered in a starting zone from a mechanical failure in the snow pack (slab avalanche) when the forces on the snow exceed its strength but sometimes only with gradually widening (loose snow avalanche). After initiation, avalanches usually accelerate rapidly and grow in mass and volume as they entrain more snow. If the avalanche moves fast enough some of the snow may mix with the air forming a powder snow avalanche, which is a type of gravity current.

My top 10 natural disasters are:

1.       1992 Hurricane Andrew: Not very deadly but cost billions in repairs.

2.       2005 Hurricane Katrina: Deadly and cost lots of money.

3.       2008 Sichuan Earthquake with aftershocks: Killed many and cost lots of money.

4.       2008 Cyclone Nargis: Killed many and costs billions

5.       2011 Japan Earthquake and tsunami: Killed millions and costs billions to repair and everything was destroyed with a 9 on the scale of the earthquake and created a deadly tsunami.

6.       1976 Tangshan Earthquake: 7 on the scale aftershock what killed millions and costs billions in repair.

7.       2004 Indian Ocean Earthquake and Tsunami: costs billions and killed many people during the earthquake and a 9.3 earthquake.

8.       1970 Bhola Cyclone: Deadliest Cyclone in recorded history and killed millions also most people died in the massive flooding.

9.        2010 Haiti Earthquake: a 7.0 earthquake that shacked the country and killed millions.

10.   1931 China Central floods: Deadliest natural disaster in natural history and killed millions most people died from drowning.
