They can cause widespread destruction, such as the 1980 eruption of Mt St Helens. Lahars are a secondary effect of a volcanic eruption and are cement-like mudflows consisting of volcanic ash and water. They often occur in the days following an eruption when people are at their most vulnerable and with the capacity to travel up
Less rainfall means there is less water to enter into the facility and transport radioactive waste. On the negative side there are three things which cause me an unsteady feeling. First, the mountain is in an area where there has been volcanic activity. Because of the activity strong gases have entered into the ground which could cause explosions to be destructive. Secondly, the area has several faults running through the area where the proposed facility was to be built.
Gases dissolved in magma provide the motive force of volcanic eruptions, sulphurous volcanic gas and visible steam are usually the first things noticed on an active volcano as well as others that escape unseen for example through hot fumaroles, active vents, and porous ground surfaces. The limitations of taking these samples are remote location of these sites, intense and often hazardous fumes, frequent bad weather, and the potential for sudden eruptions can make regular sampling sometimes impossible and dangerous. Measuring gases remotely is possible but requires ideal weather and the availability of suitable aircraft or a network of roads around a
The Colombian volcano, Nevado del Ruiz, came to life in late 1984 with small-scale activity. Volcanologists from the US knew the danger a major eruption could pose to the surrounding area, but were unable to predict when the major event would take place because of a lack of resources. Small-scale volcanic activity continued for several months and people were not prepared to evacuate their homes on the basis of this threat. MEDC can greatly reduce the hazards of a volcano in lots of ways. These include creating an exclusion zone around the volcano, being ready and able to evacuate residents and having an emergency supply of basic provisions, such as food.
Haz Mat- Any substance or material could adversely affect the safety of the public, handlers or carriers during transportation. 1001- Acetylene; Extremely flammable gas and is unstable. as a precaution isolate the spill for at least a 100meters in all directions, and evacuate in a large spill or fire. First aide move victim to fresh air, give artificial respiration, administer o2, remove contaminated clothing. If contact was liquefied gas thaw the frozen parts with lukewarm water.
Its relatively low temperature, high silica content and leads to blockages and powerful eruptions. This can mean that the eruptions caused by thick magma can be less frequent and more difficult to predict, meaning that when an eruption does occur, it is usually with little or no warning, which can lead to catastrophic consequences as any nearby settlement will be relatively unprepared for the effects of a violent volcanic eruption. Furthermore, acidic magma is more likely to produce
Hoses can be undone, gaskets can fail, pits leak and liquids always hit the ground, repeatedly in large quantities. Fracking needs a lot of work to be done before it can begin obtaining oil. The fracking fluids have a lot of toxic chemicals and become even more contaminated when pumped down a hole as they travel through rock formations before returning to the surface as flow back. The liquids can cause ground contamination and even in small portions can contaminate shallow aquifers with hydrocarbons, toxic chemicals, heavy metals and radioactive
It’s a waste because clean water is not an abundant resource and it will eventually run out. The amount of water used per year for fracking needs to be monitored. Earlier this year in Northern Ohio, over 400,000 residents were left without safe water due to widespread contamination. Residents were even advised not to shower due to the
A dangerous cargo manifest is most commonly associated with which mode of transportation? (1 point) C. Water 19. What chemical agents primarily attack the airway and lungs, causing irritation of the entire airway from the nose to the lungs and resulting in what is commonly known as dry-land drowning? (1 point) C. Choking (CL) 20.Identify one of the difficulties of determining the specific names of hazardous materials in both facilities and transportation. (1 point) B. Placards or labels that are missing 21.Individuals should use the principles of __________, __________, and __________ to avoid chemical agents.
Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 marks) Volcanic hazards pose a risk to people and their property in both primary and secondary form. A volcano is an opening in the Earth's crust which lava, ash and gases erupt. A volcanic eruption can cause many deaths, illnesses, destruction of infrastructure, crops and livestock, all which will affect the economy and GNP of a country. There are many factors involved which cause differences in the severity of the destruction caused by a volcano, such as, locations of settlements, monitoring, plate boundaries and the economic status of a country, however these are different for each volcano around the world. I will be discussing factors that cause differences in hazards posed by volcanoes.
