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).
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 ).
It is interpreted as Australian and Indian plate lithosphere that is actively subducting northward below Sundaland, along the Sumatra and Java trenches. To the northwest it is disconnected through a slab window below the Andaman Islands from the Burma slab.In the East it connects to the Banda slab. In the west, tomographic images show that the ...
Abstract: The paper discusses the geomorphology of the Sunda Trench, an oceanic trench located in the eastern Indian Ocean along the Sumatra and Java Islands of the Indonesian archipelago.
The Sunda megathrust is curviplanar, forming an arc in map view and, at least in Sumatra, increasing in dip from 5°-7° near the trench, then increasing gradually from 15°-20° beneath the Mentawai Islands to about 30° below the coastline of Sumatra.
The Java Trench constitutes an extensive subduction zone, where the seafloor of the tectonic plate to the west is being forced under the stable plate to the east (there represented by the Sunda Shelf and the Sunda Island arc). It is an active volcanic and seismic zone.
