Slab pull: plate speed should be related to the percentage of its boundary subducting
under another plate.
That's because the speed of subduction was believed to be dependent on the strength of the subducting
plate as it bends and slides into the viscous mantle, the semi molten layer of rock beneath the Earth's crust.
Specifically, they reveal a link between seamounts and earthquakes, as seamounts are formerly active volcanoes and therefore generally are located near tectonically active plate boundaries, midocean ridges, and subducting
Local high rates of convergence at the Hellenic subduction zone (35mm/yr) are associated with back-arc spreading throughout Greece and western Turkey above the subducting
Mediterranean oceanic crust.
According to it, an earthquake of the same magnitude as the 2004 Sumatra earthquake can happen anytime in the MSZ, which lies in Balochistan along the southwestern coast of Pakistan, where the oceanic crust of the Arabian Plate is subducting
beneath the continental crust of the Eurasian Plate.
Researchers also found that the thickness of the sediment on the subducting
plate too contributes to the magnitude of earthquake and tsunami in the region.
The Arabian plate is subducting
(pushing beneath) the Eurasian plate at the Makran coast of Pakistan and Iran south of that event."
Like a bulldozer, the continent scooped up islands sitting on top of the subducting
Farallon plate that were too buoyant to sink into the mantle.

slab," Earth and Planetary Science Letters, vol.
There is no reason why nuclear waste should not be disposed of in the deep subducting
regions of the ocean where tectonic forces draw all deposits down into the magma.
We knew there was a plate subducting
there; what we didn't know was that it could fail on that scale.
Seismic tomography studies have also suggested that subducting
slabs of lithosphere tend to become stagnant in the transition zone [2, 22].
This highly technical book also deals with new theories on the dynamics of magma upwelling, the deformation behavior of rapidly subducting
oceanic plates, and the model for the Himalayan orogeny.
The potential source of local tsunami is the fault line off Makran, around 90-130 km from the nearest shore where the Arabian Tectonic Plate is slowly subducting
below the Eurasian Plate at an average rate of 19 mm per annum, they added.
