Disaster response

Disaster response refers to the actions taken directly before, during, or immediately after a disaster. The objective is to save lives, ensure health and safety, and meet the subsistence needs of the people affected. It includes warning and evacuation, search and rescue, providing immediate assistance, assessing damage, continuing assistance, and the immediate restoration or construction of infrastructure. An example of this would be building provisional storm drains or diversion dams. Emergency response aims to provide immediate help to keep people alive, improve their health and support their morale. It can involve specific but limited aid, such as helping refugees with transport, temporary shelter, and food, or it can involve establishing semi-permanent settlements in camps and other locations. It may also involve initial repairs to damage to infrastructure, or diverting it.

The response phase focuses on keeping people safe, preventing the next disasters and meeting people's basic needs until more permanent and sustainable solutions are available. The governments where the disaster has happened have the main responsibility for addressing these needs. Humanitarian organisations are often present in this phase of the disaster management cycle. This is especially true in places where the government does not have the resources for a full response.

Disaster response refers to the actions taken directly before, during or in the immediate aftermath of a disaster. The objective is to save lives, ensure health and safety and to meet the subsistence needs of the people affected.

The Business Dictionary provide a more comprehensive definition for "disaster response"; Aggregate of decisions and measures to (1) contain or mitigate the effects of a disastrous event to prevent any further loss of life and/or property, (2) restore order in its immediate aftermath, and (3) re-establish normality through reconstruction and re-rehabilitation shortly thereafter. The first and immediate response is called an emergency response.

The Johns Hopkins and the International Federation of Red Cross and Red Crescent Societies (IFRC) state: "The word disaster implies a sudden overwhelming and unforeseen event. At the household level, a disaster could result in a major illness, death, or a substantial economic or social misfortune. At the community level, it could be a flood, a fire, a collapse of buildings in an earthquake, the destruction of livelihoods, an epidemic or displacement through conflict. When occurring at the district or provincial level, a large number of people can be affected."

A recent case study of a disaster response undertaken by the IFRC can be viewed here.

The level of disaster response depends on a number of factors and particular situation awareness. Studies undertaken by Son, Aziz and Peña-Mora (2007) shows that "initial work demand gradually spreads and increases based on a wide range of variables including scale of disaster, vulnerability of affected area which in turn is affected by population density, site-specific conditions (e.g. exposure to hazardous conditions) and effects of cascading disasters resulting from inter-dependence between elements of critical infrastructure".

In the British Government's Emergency Response and Recovery guidance, disaster response refers to decisions and actions taken in accordance with the strategic, tactical and operational objectives defined by emergency responders. At a high level these will be to protect life, contain and mitigate the impacts of the emergency and create the conditions for a return to normality. Response encompasses the decisions and actions taken to deal with the immediate effects of an emergency. In many scenarios it is likely to be relatively short and to last for a matter of hours or days—rapid implementation of arrangements for collaboration, co-ordination and communication are, therefore, vital. Response encompasses the effort to deal not only with the direct effects of the emergency itself (e.g. fighting fires, rescuing individuals) but also the indirect effects (e.g. disruption, media interest).
