3.6.1. Andaman and Nicobar Islands

The Bay of Bengal island groups consist of about 572 islands/islets. These are situated roughly between 6°N-14°N and 92°E -94°E (Figure 15a). The entire group of island is divided into two broad categories – the Andaman in the north and the Nicobar in the south. They are separated by a water body which is called the Ten degree channel. It is believed that island group is an extension of submarine mountains. However, some smaller islands are volcanic in origin. Barren island, the only active volcano in India is also situated here. The coastal line has some coral deposits, and beautiful beaches. These islands lie close to equator and thus, experience equatorial climate. The islands have thick forest cover due to heavy convectional rainfall.
