The Andaman and Nicobar Islands are a union territory of India located at the southeastern edge of the Bay of Bengal.1

The islands form an arc that stretches southward for approximately 620 miles (1,000 km) between Myanmar to the north and the Indonesian island of Sumatra to the south. Specifically, the northwestern tip of Sumatra lies about 90 miles (145 km) to the southwest of Great Nicobar, the southernmost major island in the chain. This island arc serves as a geographical boundary, separating the Bay of Bengal to the west from the Andaman Sea to the east.123
