Welcome to the Land of Tribals the BARATANG ISLAND. A hub of Tribal people's habitats. The island belongs to the Great Andaman Chain, and with an area of 242.6 square kilometres (93.7 sq mi) it is one of the main islands of the group, a closely set archipelago in the Bay of Bengal, adjoining the Andaman Sea. Middle Andaman is to its north, and South Andaman to the south. Beaches, mangrove creeks, limestone caves, and mud volcanoes are some of the physical features. The islands of Ritchie's Archipelago lie 14 kilometres (8.7 mi) to the east. Port Blair, the capital of the Indian Union Territory of Andaman and Nicobar Islands, is located approximately 45 kilometres (28 mi) from the southern tip of Baratang. Baratang contains the only known examples of mud volcanoes in India. These mud volcanoes have erupted sporadically, with recent eruptions in 2005 believed to have been associated with the 2004 Indian Ocean earthquake. The previous major eruption recorded was on 18 February 2003. The locals call this mud volcano jalki. There are other volcanoes in the area, the Barren Island volcano which is the only active volcano in South Asia, and the Narcondum volcano which has been classified as a dormant volcano by the Geological Survey of India.
