Seamount Subduction and Earthquakes [PDF]

Oceanography, 2010
Seamounts are ubiquitous features of the seafloor that form part of the fabric of oceanic crust. When a seamount enters a subduction zone, it has a major affect on forearc morphology, the uplift history of the island arc, and the structure of the ...

Tectonic evolution of a continental collision zone: A thermomechanical numerical model [PDF]

, 2004
We model evolution of a continent-continent collision and draw some parallels with the tectonic evolution of the Himalaya. We use a large-scale visco-plasto-elastic thermomechanical model that has a free upper surface, accounts for erosion and deposition

Plume‐Driven Subduction Termination in 3‐D Mantle Convection Models

Geochemistry, Geophysics, Geosystems
The effect of mantle plumes is secondary to that of subducting slabs for modern plate tectonics when considering plate driving forces. However, the impact of plumes on tectonics and planetary surface evolution may nonetheless have been significant.

Hypocenter estimation for 14 earthquakes in south-central Alaska (1929-1975) [PDF]

, 2018
We provide results from an analysis of 14 historical earthquakes in the region of Cook Inlet and Susitna, south-central Alaska. Using global arrival times of P and S waves, we estimate probabilistic hypocenters using the code NonLinLoc.

The Role of Slab Remnants in Modulating Free Subduction Dynamics: A 3‐D Spherical Numerical Study

Geochemistry, Geophysics, Geosystems
Seismic tomography of Earth's mantle images abundant slab remnants, often located in close proximity to active subduction systems. The impact of such remnants on the dynamics of subduction remains underexplored. Here, we use simulations of multi‐material

Creep of Talc at Subduction Zone Conditions: Implications for Slow Slip and Strength of the Lithosphere

Geophysical Research Letters
Talc can strongly influence the rheological properties of the subduction interface. Despite geologic evidence for talc at the interface, and proposed links between its rheology and slow slip events, few experiments have been conducted on talc at relevant
