At last for conservations margins, the tension build up when plate are grinding past each other get stuck. Afterwards the plate will finally jerk past each other and sending out shock waves which is vibrations which is earthquakes. They both create lots of impact. For examples for the volcano eruption in Montserrat which is a LEDC, it cause 19
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
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
The extended holding of the waste fluid in the pits could lead to their seepage into the ground, especially if the pits are not lined with plastic. This contaminates the water sources around. In addition, any overflows, for instance caused by heavy rains, allows the fluid to contaminate water in the sources. Large volumes of fluid is required (thousands of gallons of water is used per well) and its disposal is an issue too (Schmidt, 2011). Proper disposal methods should be effected to ensure the water aquifers around do not get contaminated.
Furthermore, the influx of chemicals brought deep into the ground for extraction purposes have mixed with ground water, leading to lethal contamination of local drinking water. Amongst these results, fracking often yields high amounts of methane gases to the atmosphere. If fracking continues at high rates it will evidently threaten local habitats while also contaminating ground waters and while polluting
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.
Secondary effects include respiration problems from the plumes of smoke, land slides from soil erosion, and economic losses. As the fires burn large plumes of smoke begin to saturate the air and make the quality of air very poor for breathing. According to (usgs.gov) over 70% of people were affected by respiratory problems from poor air quality in and around the San Diego area during the 2007 wildfires. Another secondary impact of wildfires is soil erosion. Soil erosion occurs when the land is depleted of valuable nutrients making it susceptible to landslides and mudslides in the wet
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 . As it joins with trapped seawater and sediment, it melts the overlying continental crust, and the magma plumes rise to the surface. They contain more silica so are more viscous, which plugs up the volcano, meaning pressure build up. This is why these volcanoes are so explosive. Another type of plate boundary are constructive, which is the margin between two diverging plates where new magma
They may be initiated when a drill hole penetrates a confined, high-pressure aquifer. Despite efforts to contain the resulting flows, such drill holes sometimes flow out of control or they may even "blow" out with considerable force (similar blowouts can happen when oil or gas wells are drilled, and zones of high-pressure fluids - liquids or gases - are encountered). The flows may continue for several months, or even years, resulting in considerable amounts of water and washed material being carried upward to the surface of the ground. References Bluemle, J.

These include.... * The eruption had left destruction in its wake, it created a ‘Pyroclastic Flow’ or ‘Nuée ardente’ (Glowing Cloud). This is a cloud of volcanic debris, made up of solid, semi solid and hot, expanding gases. The cloud behaves like a liquid, flowing down the slope of the volcano. It can reach up to and above 100Km/h and so destroys everything in its path. The pyroclastic flow from Mt.
