Messenger Cyclone LamPam and now Nathan — natural disasters have filled our news in recent weeks. They wreak havoc in poor and vulnerable communities and cost billions in recovery and aid funding. These disasters happen when a natural hazard — such as a cyclone, bushfire or earthquake — damages human systems.
Blizzard Blizzards are severe winter storms characterized by heavy snow and strong winds. When high winds stir up snow that has already fallen, it is known as a ground blizzard.
Blizzards can impact local economic activities, especially in regions where snowfall is rare. The Great Blizzard of affected the United States, when many tons of wheat crops were destroyed, and in Asia, Afghanistan blizzard and the Iran blizzard were also significant events.
The Superstorm originated in the Gulf of Mexico and traveled north, causing damage in 26 states as well as Canada and leading to more than deaths. The determining factor on which term is used is based on where they originate. In the Atlantic and Northeast Pacific, the term "hurricane" is used; in the Northwest Pacific it is referred to as a "typhoon" and "cyclones" occur in the South Pacific and Indian Ocean.
The deadliest hurricane ever was the Bhola cyclone ; the deadliest Atlantic hurricane was the Great Hurricane of which devastated Martinique, St. Drought Drought is the unusual dryness of soil caused by levels of rainfall significantly below average over a prolonged period.
Hot dry winds, shortage of water, high temperatures and consequent evaporation of moisture from the ground can also contribute to conditions of drought. Droughts result in crop failure and shortages of water. Well-known historical droughts include the — Millennium Drought in Australia led to a water supply crisis across much of the country.
As a result, many desalination plants were built for the first time see list. Inthe State of Texas lived under a drought emergency declaration for the entire calendar year and severe economic losses.
Thunderstorm Severe storms, dust clouds, and volcanic eruptions can generate lightning. Apart from the damage typically associated with storms, such as winds, hail, and flooding, the lightning itself can damage buildings, ignite fires and kill by direct contact. Especially deadly lightning incidents include a strike in Ushari Dara, a remote mountain village in northwestern Pakistanthat killed 30 people,  the crash of LANSA Flight which killed 91 people, and a fuel explosion in Dronka, Egypt caused by lightning in which killed Hail Hailstorms are precipitation in the form of ice, with the ice not melting before it hits the ground.
Hailstones usually measure between 5 millimetres 0. Heat wave A heat wave is a period of unusually and excessively hot weather.
The worst heat wave in recent history was the European Heat Wave of A summer heat wave in Victoria, Australia, created conditions which fuelled the massive bushfires in The bushfires, collectively known as "Black Saturday", were partly the act of arsonists.
The Northern Hemisphere summer resulted in severe heat waves, which killed over 2, people. It resulted in hundreds of wildfires which caused widespread air pollution, and burned thousands of square miles of forest.
A classic anvil-shaped, and clearly-developed Cumulonimbus incus See also: List of tornadoes and tornado outbreaks A tornado is a violent and dangerous rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloudor the base of a cumulus cloud in rare cases.
It is also referred to as a twister or a cyclone,  although the word cyclone is used in meteorology in a wider sense, to refer to any closed low pressure circulation.Statistical Analysis of Natural Disasters and Related Losses (SpringerBriefs in Earth Sciences) - Kindle edition by V.F.

List of natural disasters by death toll. Jump to navigation Jump to search. A Note: Measuring the number of deaths caused by a heat wave requires complicated statistical analysis, since heat waves tend to cause large numbers of deaths among people weakened by other conditions.
As a result, the number of deaths is only known with . Chapter 39 - Disasters, Natural and Technological DISASTERS AND MAJOR ACCIDENTS.
Pier Alberto Bertazzi. Type and Frequency of Disasters.
In , the 44th General Assembly of the United Nations launched the decade for the reduction of frequency and impact of natural disasters (Lancet ).
The study of disaster statistics and disaster occurrence is a complicated interdisciplinary field involving the interplay of new theoretical findings from several scientific fields like mathematics, physics, and computer science. Statistical studies on the mode of occurrence of natural disasters.

Natural disasters don't matter for the reasons we think they do. They generally don't kill a huge number of people. Most years more people kill themselves than are killed by Nature's tantrums. A global catastrophic risk is a hypothetical future event which could damage human well-being on a global scale, even crippling or destroying modern civilization.
An event that could cause human extinction or permanently and drastically curtail humanity's potential is known as an existential risk.. Potential global catastrophic risks include anthropogenic risks, caused by humans (technology.
