Barren Island is situated approximately 135 kilometers northeast of Port Blair in the Andaman Sea. As the sole active volcano in South Asia, its geographical importance is immense for Indian geologists. The volcano rises from the seabed and is part of a volcanic chain that extends from Myanmar to Indonesia. Its first recorded eruption was in 1787 and it has seen renewed activity in the 21st century. The island is uninhabited and consists of a caldera with a central cinder cone, providing a unique site for studying island-arc volcanism and tectonic plate movements in the eastern Bay of Bengal.
