A STRONG underwater wave might have been what caused an Indonesian submarine to descend quickly and sink to a depth of 850m in the north of Bali last week, killing all 53 crew members on board.

Two senior naval officers said the movement of a strong internal wave in the spot where the submarine was reported missing was on the image report of Japanese weather satellite Himawari-8 as well as a European one.
