The Sunda Trench, earlier known as, and sometimes still indicated as the Java Trench, is located in the northeastern Indian Ocean, with a length of 2,600 kilometres (8,500,000 ft). The maximum depth of 7,725 metres (25,344 ft) (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).
