Volcanoes were seen as a sign of wrath from God in the ancient days. The volcanic eruptions remind us that this earth we live in is merely a planet that keeps changing its geology frequently. Volcanoes are basically “A fissure in the earth’s crust (or in the surface of some other planet) through which molten lava and gases erupt”. This is the dictionary meaning of the word Volcano. They are located along the edges of tectonic plates. They bring the boiling magma, ash and gases below the surface of the earth and explode violently in response to shifts in the tectonic plates. The Most Active and Dangerous Volcanoes around the world have been terrific and at the same time they pave way for various researches to the scientist.
