The 2004 Indian Ocean earthquake and tsunami was triggered by a megathrust earthquake along the convergent boundary of the Indian plate and Burma microplate and killed over 200,000 people. The 2011 tsunami off the coast of Japan , which caused 16,000 deaths and did US$360 billion in damage, was caused by a magnitude 9 megathrust earthquake ...
Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This ...
Oceanic trench formed along an oceanic-oceanic convergent boundary The Mariana Trench contains the deepest part of the world's oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate.
An oceanic trench is a type of convergent boundary at which two oceanic lithospheric slabs meet; the older (and therefore denser) of these slabs flexes and subducts beneath the other slab. Oceanic lithosphere moves into trenches at a global rate of about a tenth of a square meter per second.
The IBM arc system is an excellent example of an intra-oceanic convergent margin (IOCM). IOCMs are built on oceanic crust and contrast fundamentally with island arcs built on continental crust, such as Japan or the Andes. Because IOCM crust is thinner, denser, and more refractory than that beneath Andean-type margins, study of IOCM melts and ...
During this period of time the Australian-Pacific boundary underwent a transformation from mid-ocean ridge to a strike-slip fault and lastly at 20.1 Mya to a transpression convergent boundary. [ 5 ] Then 10.9 Mya, the Macquarie triple junction evolved into a ridge–trench–fault triple junction due to the alteration of the Australian ...
The Aleutian Trench (or Aleutian Trough) [1] is an oceanic trench along a convergent plate boundary which runs along the southern coastline of Alaska and the Aleutian islands. The trench extends for 3,400 kilometres (2,100 mi) from a triple junction in the west with the Ulakhan Fault and the northern end of the Kuril–Kamchatka Trench , to a ...
The trench is a result of a convergent plate boundary, where the eastern edge of the oceanic Nazca plate is being subducted beneath the continental South American plate. [1] The trench is also a part of the Chile triple junction , an unusual junction that consists of a mid-oceanic ridge and the Chile Rise being subducted under the South ...
