I will be discussing factors that cause differences in hazards posed by volcanoes. I believe the most important factor is the location of a volcano and the type of volcano. The most explosive and therefore dangerous volcanoes are found on destructive plate boundaries (Over 80% of the worlds volcanoes occur at these boundaries) for example the eruption of the Nevado del Ruiz in Colombia on the 13th November in 1985 which killed over 25000 residents of Arenas and Armero. At destructive plate margins, the oceanic crust is denser than continental crust and is therefore subducts under the continental crust. Due to high temperatures in the mantle of around 3000 degrees centigrade, this oceanic crusts melts and then rises due to the convection currents in the aesthenosphere .
About 42 percent of the amount of Agent Orange that we used was devoted to crop destruction; the products of hours of hard work were demolished within seconds. Agent Orange caused many people to starve to death. It has been reported, by the New York Times, that the herbicide destroyed 75 percent of the rice crops. Because people’s homes and crops were being destroyed, they were left homeless and hungry on the
b) The dangers associated with not following safe practices. Hazardous Substances are used in many workplaces and take many different forms. Exposure to hazardous substances can affect the body in many different ways. Skin contact, inhalation and ingestion can cause damage. The Control of Substances Hazardous to Health Regulations (known as COSHH) says that employers must identify which hazardous substances are present in the work place.
About 1.7 billion people live in absolute poverty. Relative poverty is the condition of having fewer resources or less income than others within a society or country, or compared to worldwide averages. Dictionary.com has described poverty as the state or condition of having little or no money, goods, or means of support; condition of being poor; indigence. About 25,000 people die every day of hunger or hunger-related causes, according to the United Nations. As a group we have concluded that a person is consider in poverty when they cannot afford the basic necessities of life including: food, shelter, drinking water, and clothes.
Case study: 2005 Kashmir Earthquake The 2005 earthquake of the Kashmir region is the 17th deadliest earthquake ever recorded, killing approximately 79,000 people from India, Pakistan and Afghanistan alike. The earthquake measured 7.6 on the Richter scale. Earthquake area [pic] Fact file When: 8th October 2005 Where: Kashmir (India, Afghanistan & Pakistan) Magnitude: 7.6 Deaths: 79,000 (totalled from primary and secondary effects of the earthquake) Injuries: 106,000 Area of destruction 31.4km² Why did it happen? [pic] The earthquake happened because the region is on a collision boundary of the Indian and Eurasian plates (the two plates that form the Himalayas). These two normally push together steadily, but when they jam the pressure builds up, and then is realised as an earthquake, such as the Kashmir quake [pic] How were the people affected?
The initial impact was devastating which left about 300,000 people homeless out of a population of about 410,000. Many of the people were evacuated to nearby cities, and the others lived in makeshift tents on the beach of North beach. In fact years later in 1908 these refugee camps were still in operation. The overall cost of the damages was estimated at the time to be 400 million US Dollars (around 8.2 Billion present Dollars). The fires that were a direct result from the main shock and the aftershocks were just as damaging because of the uncontrollable burning from ruptured gas lines.
Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 marks) A hazard is a situation that poses a level of threat to life, health, property or environment, all of which can be compromised by a volcano. A volcanic eruption can cause many deaths, illnesses, destruction of property, crops, and livestock, also the economy of an area may be affected, amongst other things. However, there are many factors involved which can cause differences in the severity of destruction caused by a volcano such as, settlement, monitoring, plate boundaries and the economic status of a country; which would be different for every single volcano around the world. One factor that would cause differences in the hazards posed by volcanoes is settlement, which includes where people chose to live in relation to a volcano. For example, in Indonesia many people settle near Mount Merapi because of the rich and fertile soil favoured for farming.
The Sociological Imagination and Hurricane Sandy: Was Hurricane Sandy a Personal Trouble or Public Issue? Hurricane Sandy hit the United States on October 29, 2012, destroying the Northeast. Soon after landfall, media started calling this perfect storm “Superstorm Sandy” and “Frankenstorm.” Killing over one hundred people, this thirteen-day storm, affected twenty-four states, including the entire eastern seaboard from Florida to Maine and west across the Appalachian Mountains to Michigan and Wisconsin. The most severe damage was in New Jersey and New York. Sandy left tens of thousands homeless, crippled mass transit, triggered paralyzing gas shortages, inflicted billions of dollars in infrastructure damage and cut power to more than 8million homes.
It can cause cold sores, mouth ulcers, and skin lesion or rash on the lips, mouth, and gums. Most of the people of the United States get infected by the age of twenty and almost 70% of the world population is seropositive for Herpes Simplex Virus type 1, which means that almost 2/3 of the population of the world has the virus in their bodies they might not show the symptoms, but they can infect other people with contact of saliva or direct contact with skin (Rajiv, Saini, Saini Santosh,
The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1348 and 1350. Although there were several competing theories as to the etiology of the Black Death, recent analysis of DNA from victims in northern and southern Europe indicates that the pathogen responsible was the Yersinia pestis bacterium, which causes the Bubonic plague, although these were different, previously unknown ancestral variants of those identified in the 20th century. The Black Death is thought to have started in China or central Asia, before spreading west. It is estimated to have killed 25 million people or 30% of the population of China. The plague then travelled along the Silk Road and reached the Crimea by 1346.
