Prevention for Volcano Eruption When people hear news about volcano, they may naturally think of the bad things that might have occurred. The reason is that volcano is one of the most dangerous naturally disasters that human being need to face. After I learned volcano in EAPS class, I became interested in the volcano since I think the eruption of volcano is a fascinating scenery. However, volcanoes are able to cause catastrophes when they get "mad". I am going to do some researches and find out why volcanoes erupt and how to foresee these eruptions. Scientifically, a volcano is a mountain that extends down to a pool of magma between the crust and mantle. Basically, a volcano is a hole in the Earth from which magma can erupt. And scientists …show more content…
I believe no one wants to live close to the volcano. Data from the Smithsonian Institution’s (SI) Global Volcanism Program compiles shows that between the years 1600 AD to 2010, there are 533 incidents that have caused a combined total of 278,880 fatalities, at 198 volcanoes across 38 countries. So active volcano cause serious disaster to human being. Now let 's see why volcanoes erupt. Simplest answer is that magma is trying to float to the surface since magma is less dense than rocks. However, the process of each eruption is every different. There are two types of eruptions which are explosive eruption and fissure eruption. According to Basicplanet, "an explosive eruption happens because of a buildup of gas under very viscous slow flowing and thick magma. These types of eruption are very violent and rapid; more often they will spew volcanic material, lava and ash onto a large area. A fissure or a quiet eruption will emit a lot of lava from a fracture or fissure. Because lava would usually have a low viscosity, the gas can easily escape." Unlike the earthquake, volcanic eruptions have some good effects which are producing spectacular scenery to tourists and rich soils for …show more content…
Hence, there are nine Volcanic Ash Advisory Centres around the world which use satellites to help track volcanic ash clouds and provide warnings for aircraft." For example, when the Icleandic volcano (Eyjafjallajokull) erupted in 2010 air traffic was disrupted all over Europe. Moreover, volcanic eruptions produce massive clouds of ashes into the troposphere, later, they drift upward to stratospheric. The result is that stratosphere ozone molecules will be destroyed during this process by high concentration of bromine and chlorine from ashes. Volcanic ash is abrasive, so during and after ash fall, people are easily experience eye discomfort or irritation, especially among those that use contact lenses. It is difficult or sometimes impossible to drive in ashy conditions due to slippery road and poor visibility which cause accidents and individuals’ injuries. Furthermore, inhalation of ash can exacerbating pre-existing lung disease. Since mankind has no ability to stop inevitable volcanic eruptions at least so far, the only thing we can do is to predict volcanic eruptions and evacuate citizens timely. Under the “developments in volcanology, such as improved monitoring techniques, better understanding
