The trench stretches from the Lesser Sunda Islands past Java, around the southern coast of Sumatra to the Andaman Islands, and forms the boundary between the Indo-Australian Plate and Eurasian Plate (more specifically, Sunda Plate).
A Map of the Sunda Trench, showing the position of Anak Krakatau at an inflection point in the subduction of the Indo-Australian plate beneath Eurasia.
1 paź 2019 · The Java Trench, also known as the Sunda Trench, is located south and west of the islands of Java and Sumatra in the eastern Indian Ocean, and is in excess of 3200 km in length. The trench is formed as the Indo-Australian Plate subducts beneath the Eurasian Plate, at a rate of between 60 and 73 mm per year (De Mets et al., 2010).

The map reveals typical features of a subduction zone: an oceanic trench, a fore-arc ridge, a fore-arc basin, and an island arc. The location of the plate boundary is marked by the Sunda Trench, a narrow band of very deep water that parallels the Sumatran coast.
