What Is A Volcano:-A volcano is a vent or opening in the earth through which hot lava and ash rise to the surface. A cone shaped mountain of erupted material around such a vent is also called a volcano. A volcano consists of a fissure in the earth’s crust, above which a cone of volcanic matter has accumulated. At the top of cone is a bowl shaped vent called a crater. The cone is formed by the deposition of molten matter or solid matter that flows or is ejected through the vent from the interior of the earth.
Recent Volcanic Eruptions:-
Several volcanoes have erupted in the past few months-two in Chile (Chaiten and Llaima) and one in Alaska (Okmok). At any given time, approximately 20-50 volcanoes are active worldwide mostly underwater. The eruption on24 Agust79 AD, destroyed the whole ancient city of Pompeii and then Pompeii remained buried for nearly 1700 years.
During A Volcano:-
Volcanoes can never be predicted or prevented. The only thing is that evacuation can be done if the volcano seems to be starting to erupt. During sudden explosions, nothing can be done.
