Volcanoes


Volcanoes

A Volcano is usually a vent in mountain through which hot substances and gases rise to surface. These mountains are usually cone shaped. Volcano is after the name of an island Volcano, which is situated at north of Sicily in the Mediterranean Sea.(American Public Health Associations , 2005). This islands name was given by the early Romans, because it emitted smoke like vapor and supposed to be the home of their god of fire called Vulcan. A volcano is a crack in the earth’s outer layer, over a cone shaped volcanic materials, is accumulated. This cone is created by the accumulation of molten or solid matters that is expelled out through the hole from the inside of the earth.
There are some ways available to predict the spill activity of a volcano. The most common method is to study the geography of area where it exists. They can produce and become a cause of earthquakes as well such as Mount Saint Helens, Washington, USA, did in 1980. 
In order to minimize the destruction by volcanoes, volcanologists regularly study various effects, for instance, increases in the warmth of the volcano, to predict eruption of volcano. There is little, humans can do to prevent a volcano to erupt, but still some attempts can be made to minimize the losses. Streams of lava can be diverted from towns and can be directed to a deserted area. Walls can be built to slow the flow of lava or lowering the lava temperature by water is to some extent possible.
