  2. Earthquake cycle - Wikipedia

    en.wikipedia.org/wiki/Earthquake_Cycle

    A diagram illustrating the interseismic, preseismic, and postseismic periods for a subduction zone earthquake cycle. The over-riding plate bends to accumulate stress during the interseismic period and rebounds back to its previous position to release stress.

  3. Megathrust earthquake - Wikipedia

    en.wikipedia.org/wiki/Megathrust_earthquake

    Subduction zone earthquakes are also known to produce intense shaking and ground movements that can last for up to 3–5 minutes. [ 14 ] In the Indian Ocean region, the Sunda megathrust is located where the Indo-Australian plate subducts under the Eurasian plate along a 5,500 kilometres (3,400 mi) fault off the coasts of Myanmar , Sumatra ...

  4. Slab (geology) - Wikipedia

    en.wikipedia.org/wiki/Slab_(geology)

    The figure is a schematic diagram depicting a subduction zone. The subduction slab on the right enters the mantle with a varying temperature gradient while importing water in a downward motion. A model of the subducting Farallon slab under North America. In geology, the slab is a significant constituent of subduction zones. [1]

    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 causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]

  6. Subduction - Wikipedia

    en.wikipedia.org/wiki/Subduction

    A study published in 2016 suggested a new parameter to determine a subduction zone's ability to generate mega-earthquakes. [71] By examining subduction zone geometry and comparing the degree of lower plate curvature of the subducting plate in great historical earthquakes such as the 2004 Sumatra-Andaman and the 2011 Tōhoku earthquake, it was ...

    Diagram of Wadati–Benioff zone, from the United States Geological Survey Seismicity cross-section, Kuril Islands subduction zone, 15 November 2006, 8.3 M w event marked as star A Wadati–Benioff zone (also Benioff–Wadati zone or Benioff zone or Benioff seismic zone ) is a planar zone of seismicity corresponding with the down-going slab in ...

    Their work will give modelers a sharper view of the possible impacts of a megathrust earthquake there — the term for a quake that occurs in a subduction zone, where one tectonic plate is thrust ...

    en.wikipedia.org/wiki/List_of_megathrust_earthquakes

    Comparison of recent and historic earthquakes by energy release. Megathrust earthquakes are large seismic events that take place along convergent plate boundaries, particularly at subduction zones. Examples of subduction zones include the Sumatra and Java trenches, Nankai Trough and Peru–Chile Trench which are frequent sources of these ...
