What is a Disaster?

Disaster is anything that can occur causing damages, an ecological disruption and deterioration of health and the health services. Disaster can be manmade or natural disasters such as floods. When disasters like flooding or tornadoes that may be accompanied by floods occur, the public health personnel and public health nurses are normally the first people who respond to the emergency, given that they are the people who understand and know the available resources used in providing first aids to the affected victims.

And it involves interaction with familiar faces, tasks, procedures, and organizations. (Auf der Heide, Erik. 1989) An emergency is generally personal in nature. A disaster is “an event associated with the impact of a natural hazard, which leads to increased mortality, illness and/or injury, and destroys or disrupts livelihoods, affecting the people or an area such that they (and/or outsiders) perceive it as being exceptional and requiring external assistance for recovery” (Cannon 1994, 29, fn.2). Finally, a catastrophe can be viewed as “…any disaster that overwhelms the ability of state, local, and volunteer agencies to adequately provide victims with such life-sustaining mass care services as food, shelter, and medical assistance within the first 12 to 24 hours.” (GAO, Disaster Management, 1993, p. 3).

According to Jack Herrmann is Asst. Professor of Psychiatry at the University of Rochester School of Medicine “Disaster management is the preparation for, response to, and recovery from disaster. While there are different understandings of Disaster Management, it is generally viewed as a cycle with the following five key phases:

A disaster is an unforeseen fatal event that causes massive disruption to the working of a community

Seismic events are occurrences in which energy is briefly released in the Earth's crust, resulting in a series of seismic waves which move through the crust. In some cases, the energy can be intense enough that it is felt in the form of an earthquake, while in other seismic events, the energy is so mild that it can only be identified with specialized equipment. A human disaster is an event directly and principally caused by one or more identifiable deliberate or negligent human action. Whereas a natural disaster is a natural event such as a flood, earthquake, or hurricane that causes great damage or loss

Disasters are human made or natural and occur sudden and unexpected. As disasters cannot be prevented, government has to be prepared for any emergency situation. According to Stanhope and Lancaster (2014), there are four stages in the disaster management: Prevention, Preparedness, Response and Recovery. According to Stanhope and Lancaster (2014, p 250), public health professionals study disaster effects on populations while American Red Cross work with local and other communities in preparedness, response and recovery phase of disaster.

A hazard can best be defined as a 'situation that poses a level of threat to life, health, property or the environment.' The overall impact of earthquakes as a natural hazard varies greatly from one place and timeframe to another. As do the types of hazards, which are categorised into primary and secondary. Primary hazards are created by the direct seismic energy of an earthquake; this could include liquefaction, slope failure and tsunamis. These primary hazards can in turn trigger secondary hazards such as floods, fires, disease and destabilisation of infrastructure. A number of factors play a part in determining the severity

An emergency is a severe, sudden and sometimes risky circumstances requiring urgent action (Salman Sawalha, 2014). Escalation of an emergency situation can lead to disaster; which is an unusual event that can cause lost of life and property (Salman Sawalha, 2014). International Federation of Red Cross and Red Crescent Societies (IFRRCS) define disaster as “unexpected devastating events that disrupts the operations of a population or public which leads to huge losses and overwhelmed the affected community 's ability to respond to the situation with the resources they have at hand”. There are two main types of disaster that can lead to emergency situations; these include natural and man-made disasters.

A disaster is natural or man-made. Disaster such, as flood has been catastrophic across the United Sates, as they are occurring at unusual time. Therefore, local, states and federal government should begin preparing, planning and create a policy for such times as these, because it is becoming more and more normal for cities to flood. According to Flood Facts, in terms of lives lost and property damaged, floods are just behind tornadoes as the top natural disaster. In the United States, flood damages totaled $8.41 billion in 2011. There were 113 flood-related deaths. Floods can affect any area to some degree; wherever rain falls, flooding can occur.

Disasters, whether natural or manmade, can happen anytime and anywhere, without warning. An earthquake, hurricane, tornado, fire, or hazardous material spill or even an act of terrorism can happen

Due to diverse geo-climatic conditions prevalent in different parts of the globe, different types of natural disasters like floods, droughts, earthquakes, cyclones, landslides, and volcanoes etc may strike according to the vulnerability of the area.

While natural disasters such as floods, drought and hurricanes are commonly thought to occur due to environmental forces such as weather, climate and tectonic movements; a deeper investigation into the ‘disaster’ displays other contributing forces. Human factors have a large, if not equal, contribution to the occurrance and outcome of such disasters (Pelling, 2001). As Pelling (2001) argues, there is both a physical and human dimension to ‘natural disasters’. The extent to which the natural occurrence of a physical process, such as a flood or earthquake, impacts on society is constructed by that society, creating a ‘disaster’ as measured by a

Natural disasters may be defined as natural catastrophes which cause great damage by disrupting the functioning of a society thus rendering the country incapable of coping through using its own resources as there is a need for outsider assistance in order to effectively preserve lives and the environment. Conversely, Natural hazards are natural phenomena that are potential threats to people within a society, structures or economic assets and may cause disaster. Natural disasters are inevitable and ubiquitous worldwide. Within the Caribbean, they are chiefly present in the forms of hurricanes, earthquakes, floods, droughts, and volcanoes. The great damages caused by natural disasters may be divided into three categories: social, economic

Natural disasters are anything from floods, earthquakes, volcanoes, hurricanes, tornadoes, wildfires, or anything else nature could develop that causes massive amounts of damage, or cause a large losses of life. Such events are not anything caused because of human beings, but only by the actions of atmospheric conditions, or due to the changes of continental drifts that these disasters occur. Technology has come a long way since the early days before the industrial revolution where predictions can be made and warnings can be issued. This helps reduce the amount of possible loss of lives that would occur in 21st century. However, that is not what happened during Hurricane Katrina, a category 5 Hurricane.

It's basically defined as an event of nature, which overwhelms local resources and threatens the function of process and security of the community. Generally, disasters are the ultimate test of a community’s emergency response capacity .
