The Subject of Barren Island
Barren Island is a fascinating geological landmark located in the Andaman Sea. Here is a breakdown of its significance:
Geographic Location: It is part of the Andaman and Nicobar Islands, situated about 135 km northeast of Port Blair.
Geological Context: It lies along a volcanic arc that stretches from Sumatra to Myanmar. It was formed due to the subduction of the Indian Plate beneath the Burmese Plate.
Volcanic Type: It is a stratovolcano (a conical volcano built up by many layers of hardened lava and ash).
Eruption History: After lying dormant for nearly 150 years, it erupted in 1787. In recent decades, it has become active again, with significant activity recorded in 1991, 1994–95, and as recently as 2017–2018.
Environment: True to its name, the island is mostly uninhabited by humans and has very little vegetation. Interestingly, it is known for a small population of hardy feral goats that survive there by drinking brackish water.
