Reawakening of large earthquakes in south central Chile: The 2016 Mw 7.6 Chiloé event
On 25 December 2016, the Mw 7.6 Chiloé earthquake broke a plate boundary asperity in south central Chile near the center of the rupture zone of the Mw 9.5 Valdivia earthquake of 1960. To gain insight on decadal‐scale deformation trends and their relation

Plate coupling and strain in the far western Aleutian arc modeled from GPS data
The Aleutian and Kuril‐Kamchatka arcs meet at a triple junction of the Pacific (PAC), Bering (BER), and North American (NAM) plates. We invert GPS observations from the westernmost Aleutian (Komandorsky) Islands and Kamchatka for the fault locking depth ...

The secret to starting subduction is ... subduction
Caroline Eakin, ANU The Earth's biggest earthquakes and most explosive volcanoes occur at subduction zones" where a tectonic plate (the seafloor itself) sinks bank into the Earth's interior. We've been able to compile 100 million years of existing evidence for Subduction Zone Initiation (SZI).

Modeling of residual spheres for subduction zone earthquakes: 1. Apparent slab penetration signatures in the NW Pacific caused by deep diffuse mantle anomalies [PDF]
We have computed focal residual spheres for 145 subduction zone earthquakes along the northwest edge of the Pacific using regional and global mantle velocity models from tomographic inversions.

Ophiolites in the Central Asian Orogenic Belt record Cambrian subduction initiation processes
Subduction initiation remains elusive because no present example exists. Ophiolites formed over nascent subduction zones in the past provide the key to constraining the processes of subduction initiation.

Do submesoscale frontal processes ventilate the oxygen minimum zone off Peru?
The Peruvian upwelling system encompasses the most intense and shallowest oxygen minimum zone (OMZ) in the ocean. This system shows pronounced submesoscale activity like filaments and fronts.

The Ability of Significant Tidal Stress to Initiate Plate Tectonics [PDF]
Plate tectonics is a geophysical process currently unique to Earth, has an important role in regulating the Earth's climate, and may be better understood by identifying rocky planets outside our solar system with tectonic activity.

Onset of double subduction controls plate motion reorganisation
Face-to-face double subduction systems, in which two oceanic plates subduct toward each other, are essential elements of plate tectonics. Two subduction zones in such systems are typically uneven in age and their spatially and temporally variable ...
