Introduction:
Natural disaster is a sudden and terrific event in nature (such as a hurricane, tornado, flood, heat waves,typhoon) that usually results in serious damage and a huge amount of deaths.
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 .
Bangladesh is one of the largest deltas in the world which is highly Penetrable to Natural Disasters because of its Geographical location, Flat and low-lying landscape, Poverty, Population density, Illiteracy, Lack of Institutional setup etc. Similarly the Physical, Social as well as Economic states of Bangladesh are very typical to any of the most Penetrable countries to Natural Disasters in the world . The total land area is 147,570 sq. km. consists mostly of Floodplains (almost 80%) leaving major part of the country (with the exception of the north-western highlands) prone to flooding in the rainy season. Moreover, the adverse affects of Climate Change – especially High Temperature, Cyclones and Sea-level Rise, Storm Surges, Salinity Intrusion, Heavy Monsoon Downpours etc. has aggravated the overall Economic Development scenario of the country to a great extent.
A natural disaster has the capability to cause large scale damage and destruction to an area. Seismic events have been known to alter landscapes and affect the livelihoods, health and development of communities. No two earthquake events are the same and the level of threat posed by an earthquake can vary due to both the human and physical factors of an area. The 2010 magnitude - 7.0 earthquake that occurred in Haiti is an example of where a natural disaster caused a previously vulnerable area to suffer tremendous loss and debilitating socio-economic impacts, to an already poverty-stricken nation.
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:
Natural disaster currently has become a large part of US economy, from tornadoes, fire, floods and hurricanes. These natural disasters have lead to death of people but also a billion dollar damage to several cities or states. According to National center of Environmental Information, in 2015 there were at least ten weather disasters that lead to property damages exceeding one billion dollar across United States. The natural disasters are found in many ways, the one most famous is Hurricane Katrina and another Hurricane Sandy. These two hurricanes are Atlantic hurricanes, Hurricane Katrina hit the Southern States and Hurricane Sandy hit near Atlantic City affecting many eastern States. Although the two hurricanes have occurred in separate years, yet they have caused a lot of damage in large cities leaving thousands of people without home. Furthermore due to these natural disasters has questioned the government how to prepare for natural disaster in near future. The hurricane Katrina and Hurricane Sandy are both consider Natural disaster that has lead to heavy damages but one has more devastating effect than the other.
Natural disasters are the catastrophes cause by “Mother Nature”, which is often difficult to forecast or manage (Morrison, et al 2014). Examples of
According to FEMA in Professor Rion’s PowerPoint slides, a disaster is “An occurrence that has resulted in property damage, deaths, and/or injuries to the community” (FEMA, 1990). I personally believe this definition is the best because not every disaster has to have a certain amount of deaths to occur or a specific number of injuries. I also like this definition because it fits to the disaster that happened in my hometown over a year ago.
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
To figure out the difference between a hazard, an emergency, and a disaster we will first need the definition for each. For this, we will be using the definitions found in the book Introduction to Emergency Management. According to the book, a “Hazard refers to the potential for extreme events to affect people, property and the natural environment in a given location.” An emergency is “a Minor event that causes a few casualties and a limited amount of property damage or an imminent event that will likely strike soon. Whereas a “Disaster is reserved for events that produce more losses than a community can handle.” (Lindell). Knowing this we can determine that the main difference between these definitions is the level in which they affect a given
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
A preliminary analysis of the sea level of Bangladesh was done to examine the one-metre rise in sea level (Huq et al.1995). Huq and colleagues (1995) conducted a study that included data on topological maps, tidal tales, satellite images, aerial photos, and hydrographic maps. Thematic maps were used to estimate the effect of a one-meter sea-level rise on agriculture, population, and infrastructure. Locations experiencing subsidence included the Chalan Beel, Dhaka Depression, and the Khulna Sundarbans area with
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.
