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 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).
