EmergencyAn emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency.
Hurricane KatrinaHurricane Katrina was a devastating that resulted in 1,836 fatalities and caused damage estimated between 97.4billionto145.5 billion in late August 2005, particularly in the city of New Orleans and its surrounding areas. At the time, it was the costliest tropical cyclone on record, tied now with Hurricane Harvey of 2017. Katrina was the twelfth tropical cyclone, the fifth hurricane, and the third major hurricane of the 2005 Atlantic hurricane season. Crisis managementCrisis management is the process by which an organization deals with a disruptive and unexpected event that threatens to harm the organization or its stakeholders. The study of crisis management originated with large-scale industrial and environmental disasters in the 1980s. It is considered to be the most important process in public relations. Three elements are common to a crisis: (a) a threat to the organization, (b) the element of surprise, and (c) a short decision time.
Environmental disasterAn environmental disaster or ecological disaster is defined as a catastrophic event regarding the natural environment that is due to human activity. This point distinguishes environmental disasters from other disturbances such as natural disasters and intentional acts of war such as nuclear bombings. Environmental disasters show how the impact of humans' alteration of the land has led to widespread and/or long-lasting consequences. These disasters have included deaths of wildlife, humans and plants, or severe disruption of human life or health, possibly requiring migration.
Natural disasterA natural disaster is the highly harmful impact on a society or community following a natural hazard event. Some examples of natural hazard events include: flooding, drought, earthquake, tropical cyclone, lightning, tsunami, volcanic activity, wildfire. A natural disaster can cause loss of life or damage property, and typically leaves economic damage in its wake. The severity of the damage depends on the affected population's resilience and on the infrastructure available.
Disaster recoveryDisaster recovery is the process of maintaining or reestablishing vital infrastructure and systems following a natural or human-induced disaster, such as a storm or battle. It employs policies, tools, and procedures. Disaster recovery focuses on information technology (IT) or technology systems supporting critical business functions as opposed to business continuity. This involves keeping all essential aspects of a business functioning despite significant disruptive events; it can therefore be considered a subset of business continuity.
DisasterA disaster is a serious problem occurring over a period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Disasters are routinely divided into either "natural disasters" caused by natural hazards or "human-instigated disasters" caused from anthropogenic hazards. However, in modern times, the divide between natural, human-made and human-accelerated disasters is difficult to draw.
Emergency shelterAn emergency shelter is a place for people to live temporarily when they cannot live in their previous residence, similar to homeless shelters. The main difference is that an emergency shelter typically specializes in people fleeing a specific type of situation, such as natural or man-made disasters, domestic violence, or victims of sexual abuse. A more minor difference is that people staying in emergency shelters are more likely to stay all day, except for work, school, or errands, while homeless shelters usually expect people to stay elsewhere during the day, returning only to sleep or eat.
Homeland securityHomeland security is an American national security term for "the national effort to ensure a homeland that is safe, secure, and resilient against terrorism and other hazards where American interests, aspirations, and ways of life can thrive" to the "national effort to prevent terrorist attacks within the United States, reduce the vulnerability of the U.S. to terrorism, and minimize the damage from attacks that do occur." According to an official work published by the Congressional Research Service in 2013, the "Homeland security" term's definition has varied over time.
HumanitarianismHumanitarianism is an active belief in the value of human life, whereby humans practice benevolent treatment and provide assistance to other humans to reduce suffering and improve the conditions of humanity for moral, altruistic, and emotional reasons. One aspect involves voluntary emergency aid overlapping with human rights advocacy, actions taken by governments, development assistance, and domestic philanthropy.
