Sunda Trench Sunda Trench The Sunda Trench, earlier known as and sometimes still indicated as the Java Trench, is an oceanic trench located in the Indian Ocean near Sumatra, formed where the Australian-Capricorn plates subduct under a part of the Eurasian Plate. It is long. Its maximum depth (at 10°19'S, 109°58'E, about 320 km south of Yogyakarta), is the deepest point in the Indian Ocean. The trench stretches from the Lesser Sunda Islands past Java, around the southern coast of Sumatra on to the Andaman Islands, and forms the boundary between Indo-Australian Plate and Eurasian plate (more specifically, Sunda Plate).

South Sandwich Trench 965 km long and has a maximum depth of 8,428 meters below sea level. This location, at 55°40'S, 025°55'W, is called Meteor Deep. It is 122 km northeast of Zavodovski Island. The southernmost portion of the South Sandwich Trench reaches south of 60°S and therefore into the Southern Ocean, thereby containing the maximum depth of that Ocean at 60°00'S, 024°W, with a depth of 7,235 meters.
