On the Scales of Dynamic Topography in Whole‐Mantle Convection Models

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Mantle convection shapes Earth's surface by generating dynamic topography. Observational constraints and regional convection models suggest that surface topography could be sensitive to mantle flow for wavelengths as short as 1,000 and 250 km ...

Multiple Slabs and Complex Mantle Flows in the Molucca Sea Subduction Zone

open access: yesGeochemistry, Geophysics, Geosystems
The Molucca Sea subduction zone is unique for its active divergent double‐subducted slab located in the north of the Java and Banda subduction zones. The spatial proximity of these subduction zones would cause a complex mantle flow field.

Reawakening of large earthquakes in south central Chile: The 2016 Mw 7.6 Chiloé event

open access: yesGeophysical Research Letters, 2017
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

Subduction Initiation at the Corner of Small Oceanic Basins

open access: yesGeophysical Research Letters
In Southeast Asia, emerging subduction zones often appear to begin at the corners of small oceanic basins, which have a triangular‐indenter continent–ocean boundary geometry.

Plate coupling and strain in the far western Aleutian arc modeled from GPS data

open access: yesGeophysical Research Letters, 2017
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 ...

Do submesoscale frontal processes ventilate the oxygen minimum zone off Peru?

open access: yesGeophysical Research Letters, 2016
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.
