[edit] Civil disorder

Civil disorder is a broad term that is typically used by law enforcement to describe forms of disturbance. Although civil disorder does not necessarily escalate to a disaster in all cases, the event may escalate into general chaos. Rioting has …show more content…
many causes, from antipathy over low minimum wages to racial segregation. Examples of well-known civil disorders and riots are the Poll Tax Riots in the United Kingdom in 1990; the 1992 Los Angeles riots in which 53 people died; the 2008 Greek riots after a 15-year-old boy was fatally shot by police; and the 2010 Thai political protests in Bangkok during which 91 people died.
[edit] Terrorism
Main articles: Terrorism and Asymmetric warfare
September 11 attacks
Terrorism is a controversial term with varied definitions.
One definition means a violent action targeting civilians exclusively. Another definition is the use or threatened use of violence for the purpose of creating fear in order to achieve a political, religious, or ideological goal. Under the second definition, the targets of terrorist acts can be anyone, including civilians, government officials, military personnel, or people serving the interests of governments.
Definitions of terrorism may also vary geographically. Australia, in the Security Legislation Amendment (Terrorism) Act 2002, defines terrorism as "an action to advance a political, religious or ideological cause and with the intention of coercing the government or intimidating the public", while the United States Department of State operationally describes it as "premeditated, politically-motivated violence perpetrated against non-combatant targets by subnational groups or clandestine agents, usually intended to influence an audience".[2]
[edit] War

War
War is conflict between relatively large groups of people, which involves physical force inflicted by the use of weapons. Warfare has destroyed entire cultures, countries, economies and inflicted great suffering on humanity. Other terms for war can include armed conflict, hostilities, and police action. Acts of war are normally excluded from insurance contracts and disaster planning.
[edit] Technological hazards
[edit] Industrial hazards
Industrial disasters occur in a commercial context, such as mining accidents. They often have an environmental impact. The Bhopal disaster is the world's worst industrial disaster to date, and the Chernobyl disaster is regarded the worst nuclear accident in history. Hazards may have longer-term and more dispersed effects, such as dioxin and DDT poisoning.
[edit] Structural collapse
Aftermath of the collapse of the World Trade Center
Structural collapses are often caused by engineering failures.
Bridge failures may be caused in several ways, such as under-design (as in the Tay Bridge disaster), by corrosion attack (such as in the Silver Bridge collapse), or by aerodynamic flutter of the deck (as in Galloping Gertie, the original Tacoma Narrows Bridge). Failure of dams was not infrequent during the Victorian era, such as the Dale Dyke dam failure in Sheffield, England in the 1860s, causing the Great Sheffield Flood. Other failures include balcony collapses or building collapses such as that of the World Trade Center.
[edit] Power outage
Main article: Power outage
A power outage is an interruption of normal sources of electrical power. Short-term power outages (up to a few hours) are common and have minor adverse effect, since most businesses and health facilities are prepared to deal with them. Extended power outages, however, can disrupt personal and business activities as well as medical and rescue services, leading to business losses and medical emergencies. Extended loss of power can lead to civil disorder, as in the New York City blackout of 1977. Only very rarely do power outages escalate to disaster proportions, however, they often accompany other types of disasters, such as hurricanes and floods, which hampers relief
efforts.
Electromagnetic pulses and voltage spikes from whatever cause can also damage electricity infrastructure and electrical devices.
Recent notable power outages include the 2005 Java–Bali Blackout which affected 100 million people and the 2009 Brazil and Paraguay blackout which affected 60 million people.
[edit] Fire

See also Category: Fire disasters involving barricaded escape routes
Bush fires, forest fires, and mine fires are generally started by lightning, but also by human negligence or arson. They can burn thousands of square kilometers. If a fire intensifies enough to produce its own winds and "weather", it will form into a firestorm. A good example of a mine fire is the one near Centralia, Pennsylvania. Started in 1962, it ruined the town and continues to burn today. Some of the biggest city-related fires are The Great Chicago Fire, The Peshtigo Fire (both of 1871) and the Great Fire of London in 1666.
Casualties resulting from fires, regardless of their source or initial cause, can be aggravated by inadequate emergency preparedness. Such hazards as a lack of accessible emergency exits, poorly marked escape routes, or improperly maintained fire extinguishers or sprinkler systems may result in many more deaths and injuries than might occur with such protections.

[edit] Radiation contamination
Chernobyl nuclear power plant
When nuclear weapons are detonated or nuclear containment systems are otherwise compromised, airborne radioactive particles (nuclear fallout) can scatter and irradiate large areas. Not only is it deadly, but it also has a long-term effect on the next generation for those who are contaminated. Ionizing radiation is hazardous to living things, and in such a case much of the affected area could be unsafe for human habitation. During World War II, United States troops dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki. As a result, the radiation fallout contaminated the cities' water supplies, food sources, and half of the populations of each city were stricken with disease. The Soviet republics of Ukraine and Belarus are part of a scenario like this after a reactor at the Chernobyl nuclear power plant suffered a meltdown in 1986. To this day, several small towns and the city of Chernobyl remain abandoned and uninhabitable due to fallout. In the 1970s, a similar threat scared millions of Americans when a failure occurred at the Three Mile Island Nuclear Power Plant in Pennsylvania. The incident was fortunately resolved, and the area retained little contamination.
A number of military accidents involving nuclear weapons have also resulted in radioactive contamination, for example the 1966 Palomares B-52 crash and the 1968 Thule Air Base B-52 crash.
[edit] CBRNs
Main article: CBRN
CBRN is a catch-all initialism for chemical, biological, radiological, and nuclear. The term is used to describe a non-conventional terror threat that, if used by a nation, would be considered use of a weapon of mass destruction. This term is used primarily in the United Kingdom. Planning for the possibility of a CBRN event may be appropriate for certain high-risk or high-value facilities and governments. Examples include Saddam Hussein's Halabja poison gas attack, the Sarin gas attack on the Tokyo subway and the preceding test runs in Matsumoto, Japan 100 kilometers outside of Tokyo,[3] and Lord Amherst giving smallpox laden blankets to Native Americans.[4]

The ditching of US Airways Flight 1549 was a well-publicised incident in which all on board survived
An aviation incident is an occurrence other than an accident, associated with the operation of an aircraft, which affects or could affect the safety of operations, passengers, or pilots. The category of the vehicle can range from a helicopter, an airliner, or a space shuttle. The world's worst airliner disaster is the Tenerife crash of 1977, when miscommunications between and amongst air traffic control and an aircrew caused two fully-laden jets to collide on the runway, killing 583 people.
[edit] Rail
Main article: Rail disasters
1999 Bourbonnais, Illinois train accident
A railroad disaster is an occurrence associated with the operation of a passenger train which results in substantial loss of life. Usually accidents with freight (goods) trains are not considered disasters, unless they cause substantial loss of life or property. One of the more devastating rail disasters occurred in 2004 in Sri Lanka when 1,700 people died in the Queen of the Sea train disaster. Other notable rail disasters are the 1989 Ufa accident in Russia which killed 574, and the 1917 Modane train accident in France which killed 540.
