Tertiary-Quaternary subduction processes and related magmatism in the Alpine-Mediterranean region [PDF]
During Tertiary to Quaternary times, convergence between Eurasia and Africa resulted in a variety of collisional orogens and different styles of subduction in the Alpine-Mediterranean region.

Submergence and uplift associated with the giant 1833 Sumatran subduction earthquake: Evidence from coral microatolls [PDF]
The giant Sumatran subduction earthquake of 1833 appears as a large emergence event in fossil coral microatolls on the reefs of Sumatra's outer-arc ridge.

Ocean-continent subduction cannot be initiated without preceding intra-oceanic subduction!
The formation of new subduction zones is a key element of plate tectonics and the Wilson cycle, and many different controlling mechanisms have been proposed to initiate subduction.

Water, oceanic fracture zones and the lubrication of subducting plate boundaries - insights from seismicity [PDF]
We investigate the relationship between subduction processes and related seismicity for the Lesser Antilles Arc using the Gutenberg-Richter law. This power lawdescribes the earthquakemagnitude distribution, with the gradient of the cumulative magnitude ...

Aseismic ridge subduction and flat subduction: Insights from three-dimensional numerical models
Flat subduction can significantly influence the distribution of volcanism, stress state, and surface topography of the overriding plate. However, the mechanisms for inducing flat subduction remain controversial.

Triggered seismicity associated with the 1990 Nicoya, Costa Rica, M-w=7.0 earthquake [PDF]
The 25 March 1990 (M-w = 7.0) subduction megathrust earthquake that occurred offshore the Nicoya Peninsula, Costa Rica, produced a large number of aftershocks on the subduction plate interface as expected and preceded an unusual sequence of earthquakes ...

Initiation of new subduction zones is an integral part of Earth's plate tectonics regime. It is generally accepted that the negative buoyancy of sufficiently old oceanic lithosphere provides the primary driving force for subduction initiation.

Plate tectonics: When ancient continents collide [PDF]
The geological record preserves scant evidence for early plate tectonics. Analysis of eclogites — metamorphic rocks formed in subduction zones — in the Trans-Hudson mountain belt suggests modern-style subduction may have operated 1,800 million years ...

Control of Subduction Zone Age and Size on Flat Slab Subduction
Flat slab subduction is an enigmatic style of subduction where the slab attains a horizontal orientation for up to several hundred kilometers below the base of the overriding plate.
