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). The trench is considered to be part of the Alpide belt as well as one of oceanic trenches around the northern ...
The Sumatra Trench is a part of the Sunda Trench or Java Trench.The Sunda subduction zone (called also: the Sumatra-Andaman subduction zone) is located in the east part of Indian Ocean, and is about 300 km (190 mi) from the southwest coast of Sumatra and Java islands.
The oceanic Australian plate is subducted beneath the continental Sunda plate along the Sunda Trench. The oceanic Solomon Sea plate is subducting beneath the South Bismarck plate and the New Hebrides plate driven by the mutual movements of the Australian and Pacific plates and local spreading centres.
The Burma plate, showing boundaries with the India plate (the Sunda Trench) and the Sunda plate (through the Andaman Sea) The Burma plate is a minor tectonic plate or microplate located in Southeast Asia, sometimes considered a part of the larger Eurasian plate. The Andaman Islands, Nicobar Islands, and northwestern Sumatra are located on the ...
The Sunda plate is a minor tectonic plate straddling the equator in the Eastern Hemisphere on which the majority of Southeast Asia is located. [ 1 ] The Sunda plate was formerly considered a part of the Eurasian plate , but the GPS measurements have confirmed its independent movement at 10 mm/yr eastward relative to Eurasia.
Cold seep communities have been identified in the inner trench slopes of the western Pacific (especially Japan [39]), South America, Barbados, the Mediterranean, Makran, and the Sunda trench. These are found at depths as great as 6,000 meters (20,000 ft). [2]
The western and southern borders of Sundaland are clearly marked by the deeper waters of the Sunda Trench – some of the deepest in the world – and the Indian Ocean. [4] The eastern boundary of Sundaland is the Wallace Line , identified by Alfred Russel Wallace as the eastern boundary of the range of Asia's land mammal fauna, and thus the ...
The convergence between the Indo-Australian plate and the Sunda plate is not perpendicular to the plate boundary in this region. Instead, the two plates move at an oblique angle. Most of the convergent strain is accommodated by thrust motion at the plate boundary "megathrust" fault that defines the Sunda Trench.
