In 2013 Qusai Ayman Naser contended that Atlantis may be in the Bay of Bengal off the coast of India. His theory concerns Alexander the Great's march eastward toward India, which was not only to fight Persia, but in historical accounts was for mysterious personal reasons. Naser theorizes that this reason could possibly have been in search of the lost land of Atlantis.
The Bay of Bengal, the largest bay in the world, forms the northeastern part of the Indian Ocean. Roughly triangular in shape, it is bordered mostly by India and Sri Lanka to the west, Bangladesh to the north, and Burma (Myanmar) and the Andaman and Nicobar Islands to the east.
The Bay of Bengal occupies an area of 2,172,000 km². A number of large rivers – the Ganges and its distributaries such as Padma and Hooghly, the Brahmaputra and its distributaries such as Jamuna and Meghna, other rivers such as Irrawaddy River, Godavari, Mahanadi, Krishna and Kaveri flow into the Bay of Bengal. Among the important ports are Chennai, Chittagong, Kolkata, Mongla, Paradip, Tuticorin, Visakhapatnam and Yangon.
According to ancient Hindu scriptures, this water body has been referred to as Mahodadhi. The Bay of Bengal appears as Sinus Gangeticus or Gangeticus Sinus, meaning "Gulf of the Ganges", in ancient maps. In the 10th century the explosion of Indianized kingdoms, led by the Chola Empire, resulted in the Bay of Bengal being known as the Chola Lake. It later came to be known as Bay of Bengal after the region of Bengal.
The islands in the bay are numerous, including the Andaman Islands, Nicobar and Mergui groups of India. The Cheduba group of islands, in the north-east, off the Burmese coast, are remarkable for a chain of mud volcanoes, which are occasionally active. Great Andaman is the main archipelago or island group of the Andaman Islands, whereas Ritchie's Archipelago consists of smaller islands. Only 37, or 6.5%, of the 572 islands and islets of the Andaman and Nicobar Islands are inhabited.
Underneath the Bay of Bengal is the Indian Plate which is part of the great Indo-Australian Plate and is slowly moving north east. This plate meets the Burma Microplate at the Sunda Trench. The Nicobar Islands, and the Andaman Islands are part of the Burma Microplate. The India Plate subducts beneath the Burma Plate at the Sunda Trench or Java Trench. Here, the pressure of the two plates on each other increase pressure and temperature resulting in the formation of volcanoes such as the volcanoes in Myanmar, and a volcanic arc called the Sunda Arc. Sumatra-Andaman earthquake and Asian Tsunami was a result of the pressure at this zone causing a submarine earthquake which then resulted in a huge Tsunami.
