Environmental Hazards: Cultural, Biological, Physical and Chemical

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.

Although major disasters, such as wildfires, tornadoes, and earthquakes, are usually followed by an outpouring of

In 2005 alone 88,117 people were killed in Natural Disasters. A massive 1836 of those people died during Hurricane Katrina that struck New Orleans. Natural disasters are sometimes unpredictable and can not be avoided. It is important that communities are educated and authorities are prepared for anything.

The natural environment is, of course, not “getting its revenge”. Geophysical, meteorological, and hydrologic processes are unfolding as they have for millennia, beginning long before humans occupied the earth and continuing to the present. Given the eons-long perspective of the natural environment, it would be very difficult to identify meaningful changes in event frequency for the short time period in which scientific records are available on geological, meteorological, and hydrological phenomena. Event frequency, from an emergency management perspective, is not really the issue. It is certainly true that, over the years, more people have been affected by natural disasters and losses are becoming progressively greater. The significant feature driving these observations, however, is the extent of human encroachment into hazard prone areas. With increasing population density and changing land use patterns, more people are exposed to natural hazards and consequently our accumulated human and economic losses are increasing. Much of this exposure is a matter of choice. Sometimes people choose hazardous places, building houses on picturesque cliffs, on mountain slopes, in floodplains, near beautiful volcanoes, or along seismic faults. Sometimes people choose hazardous building materials that fail under extreme environmental stresses—for example, unreinforced masonry construction in seismically active areas. Some exposure results from constrained choices; the cheap land or

Over the course of humanity, there have been several notable types of disasters ranging from severe floods, earthquakes, tornados, fires, ice storms, bombings, tropical storms, and hurricanes. Many individuals have experienced some form of these disasters throughout their life, either natural or manmade. “Surveys suggest that 13–30% of individuals will be exposed to one or more natural disasters in their lifetime” (Jacob, 2015, p. 512). Along the eastern and southern United States coastlines, the more common disaster associated with these areas are hurricanes. “Each year, on average, 10 tropical storms, of which six become hurricanes, develop over the Atlantic Ocean, Caribbean Sea, or Gulf of Mexico from June to November. Many of these remain over the ocean; however, about five hurricanes strike the United States coastline every three years” (Hurricanes, nd, para 4). Based on this average, roughly two hurricanes per year make landfall. Depending on the severity, that is two large areas with several

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.

Our natural hazard is a hurricane. They can go up to 70 to 200 miles per hour wind speed. Each hurricane lasts up to about a week. They are huge storms that run on water. They are able producing to about 200 times of the world's electricity. Hurricane winds can rip off roofs, blow out windows and flatten buildings. and they’re notorious for making deadly weapons out of random debris. Hurricanes can also make tornadoes, which have even stronger winds. They create sink holes. There have been many hurricanes some worse than others. One of the worst hurricanes to ever occur was Hurricane Galveston.

Have you noticed the amount of natural disasters that have occurred lately? Recently, natural disasters have been happening such as hurricane Harvey, Irma, and the 7.1 magnitude earthquake Mexico experienced. Sadly, California could be next to be hit from an earthquake.

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

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 have killed more than 600,000 people and left behind trillions of dollars in damages in the last two decades, the United Nations said Monday.” (Chan) Extreme weather has caused millions of casualties and extreme damages over the years, but lately there has been an increase in severe weather events. This is causing problems in the US, with the amount of tornadoes rising in tornado alley “Tennessee experienced a 67 percent increase in tornado activity in 1983-2013 compared to the 1954-1983 time period. Oklahoma experienced a nearly 35 percent decrease in tornadoes in 1983-2013 compared to 1954-1983.”

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.

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.
