Subduction May Recycle Less Water Than Thought
A new analysis of seismic data from the Middle America Trench suggests that previous calculations have vastly overestimated the total amount of water transported to the mantle worldwide.
Using Earthquake Forensics to Study Subduction from Space
Researchers combined satellite geodetic measurements of surface motion with a new geophysical data inversion method to probe the Chilean subduction zone in the wake of the 2010 Maule earthquake.
Fault Related Anisotropy in the Hikurangi Subduction Zone
A new study provides the first high-resolution three-dimensional anisotropic P-wave velocity model of the shallow part of the Northern Hikurangi subduction zone offshore New Zealand.
By Land or Sea: How Did Mammals Get to the Caribbean Islands?
A multidisciplinary team is jointly investigating mammal evolution and subduction dynamics to unravel how flightless land mammals migrated to the Greater Antilles and other Caribbean islands.
What Controls Giant Subduction Earthquakes?
Subduction zones with a low dipping angle and thick sediments can produce giant earthquakes; this finding lets researchers estimate worst-case scenarios for coastlines around the world.
A Mechanism for Shallow, Slow Earthquakes in Subduction Zones
Slow earthquakes beneath the accretionary prism updip from the locked portion of a subduction zone can be caused by basaltic blocks embedded in a shale matrix.
What Controlled the Growth of the Southern Central Andes?
Flat-slab subduction appears to have played a minor role in the growth of the Southern Central Andes, with evidence for eastward migrating deformation.
Land Motion Offers Insights into Cascadia Earthquake Cycle
Comparing recent GPS data with a longer record of sea level along the western coast of North America allows researchers to home in on interseismic deformation above the Cascadia megathrust.
Modeling Fluid Migration in Subduction Zones
Scientists from different disciplines are working together to identify common challenges in and techniques for modeling fluid migration associated with subduction zone processes.
