Which of the following islands of India, located in the Bay of Bengal, contains India's only active volcanic vent?

💡 Solution & Explanation

Barren Island, situated in the Andaman Sea east of the main Andaman chain, contains India's only confirmed active volcano, which has recorded multiple eruptions in recent decades. Narcondam Island is a dormant volcanic cone located further north in the same archipelago. The Andaman and Nicobar islands are formed by the southward extension of the Arakan Yoma mountain arc. Active volcanism here is driven by the subduction of the Indian plate beneath the Burma microplate.
