Which Indian island group is home to India's only active volcano?
The Andaman and Nicobar Islands are home to India's only active volcano, located on Barren Island in the Andaman Sea. Situated approximately 135 kilometres northeast of Port Blair, Barren Island is part of the Andaman volcanic arc, formed by tectonic activity where the Indian Plate moves beneath the Burma Plate. The island's volcano has experienced several eruptions, including a major phase of activity in 1991, followed by further eruptions in subsequent years. It is characterized by a volcanic cone surrounded by a barren landscape, with little permanent vegetation near the crater. The island is largely uninhabited, and access is restricted due to volcanic activity and environmental considerations. Barren Island is an important geological site because it provides evidence of ongoing volcanic processes in the Indian subcontinent.
