There is a thing about nature’s wrath. After the fury subsides, it becomes all the more interesting. Yes! Andaman Island also has an active volcano. ‘Barren Island’ has erupted twice in the last two decades after being dormant for about 177 years.
A volcano is an opening, or rupture, in a planet’s surface or crust, which allows hot magma, volcanic ash and gases to escape from the magma chamber below the surface.
There is no consensus among volcanologists on how to define an “active” volcano. The lifespan of a volcano can vary from months to several million years, making such a distinction sometimes meaningless when compared to the lifespans of humans or even civilizations.
The only active volcano in India is located in Barren Island. The volcano erupted twice in recent past, once in 1991 and again in 1994-95, after remaining dormant for about 177 years. This island is about 3 kms in diameter, and has a big crater of the volcano, about half kilometer away from the shore. The island can be visited by chartered boats only with the permission of Forest Department.
