Subduction initiation by thermal–chemical plumes: Numerical studies
Physics of the Earth and Planetary Interiors, 2008 Abstract Prior suggestions for the initiation of subduction have included sediment loading, compression, and plate reconfiguration as potential triggers. Here, we investigate the possibility of subduction initiation by the interaction of the lithosphere with a buoyant mantle plume.

Cenozoic evolution of Neotethys and implications for the causes of plate motions [PDF]
, 2003 Africa-North America-Eurasia plate circuit rotations, combined with Red Sea rotations and new estimates of crustal shortening in Iran define the Cenozoic history of the Neotethyan ocean between Arabia and Eurasia. The new constraints indicate that Arabia-

The arc arises: The links between volcanic output, arc evolution and melt composition [PDF]
, 2017 Subduction initiation is a key process for global plate tectonics. Individual lithologies developed during subduction initiation and arc inception have been identified in the trench wall of the Izu–Bonin–Mariana (IBM) island arc but a continuous record ...

BONINITES THROUGH TIME AND SPACE: PETROGENESIS AND GEODYNAMIC SETTINGS
Геодинамика и тектонофизика, 2016 The article provides an overview of boninitic magmatism occurrences in space and time and shows that the boninite rock series were generated through the entire geological history of the Earth.

Dynamic interaction between tectonic plates, subducting slabs, and the mantle [PDF]
, 1997 Mantle convection models have been formulated to investigate the relation between plate kinematics and mantle dynamics. The cylindrical geometry models incorporate mobile, faulted plate margins, a phase change at 670 km depth, non-Newtonian rheology, and

A Giant Impact Origin for the First Subduction on Earth
Geophysical Research LettersHadean zircons provide a potential record of Earth's earliest subduction 4.3 billion years ago. It remains enigmatic how subduction could be initiated so soon after the presumably Moon‐forming giant impact (MGI).

The 25 October 2010 Mentawai tsunami earthquake (M_w 7.8) and the tsunami hazard presented by shallow megathrust ruptures [PDF]
, 2011 The 25 October 2010 Mentawai, Indonesia earthquake (M_w 7.8) ruptured the shallow portion of the subduction zone seaward of the Mentawai islands, off-shore of Sumatra, generating 3 to 9 m tsunami run-up along southwestern coasts of the Pagai Islands that
