Sunda Shelf

Map of Sahul and Sunda

Geologically, the Sunda Shelf (/ˈsʌndə/[1]) is a south-eastern extension of the continental shelf of Mainland Southeast Asia. Major landmasses on the shelf include the Indonesian islands of Bali, Borneo, Java, Madura, and Sumatra, as well as their surrounding smaller islands.[2] It covers an area of approximately 1.85 million km2.[3] Sea depths over the shelf rarely exceed 50 metres and extensive areas are less than 20 metres resulting in strong bottom friction and strong tidal friction.[4] Steep undersea gradients separate the Sunda Shelf from the Philippines, Sulawesi, and the Lesser Sunda Islands (not including Bali).
