Nature is a thing of beauty. But there are also many disastrous facets in the nature such as earthquakes, earth slips and floods. Volcanoes are another kind of disaster in the nature.
A volcano a kind of mountain which erupts all of a sudden, may remain harmless for centaurs, with only a faint could of smoke over its summit. Because of this people find it hard to forecast as to when a volcano is a going to blast. But when a volcano is just about to blast those around it may sense the internal rambling which grows louder and louder.
After some time a thick black foamy gas is ejected from the summit. Following that comes a very hot emulsion like liquid which is very destructive is called lava. Lava is formed by the rocks which lay deep down in the earth.
