<P> The Sunda Trench, earlier known as, and sometimes still indicated as the Java Trench, is located near Sumatra, formed where the Australian Plate subducts under a part of the Eurasian Plate . With a length of 3,200 kilometres (2,000 mi). 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). The trench is considered to be part of the Pacific Ring of Fire as well as one of a ring of oceanic trenches around the northern edges of the Australian Plate . </P> <P> There is scientific evidence that the 2004 earthquake activity in the area of the Java Trench could lead to further catastrophic shifting within a relatively short period of time, perhaps less than a decade . This threat has resulted in international agreements to establish a tsunami warning system in place along the Indian Ocean coast . </P>
