Fault geometry and slip rate analyses show deformation in the Yakima Fold Province accelerated in the Pleistocene and has remained elevated, offering new insights into earthquake recurrence intervals.
Tectonics
Evidence for Gravity Tectonics After the Great Sumatra Quake
A new method that applies structural geology principles to aftershock analyses suggests that gravity-driven motion may occur during part of the seismic cycle.
An Improved Understanding of How Rift Margins Evolve
A new seismic reflection study of the mid-Norwegian margin examines the role that low-angle, high-displacement faults play in the evolution of continental rifts.
Tracking Deep-Earth Processes from Rapid Topographic Changes
Rapid elevation-rise in Turkey, tracked by marine sediments that now sit at 1.5 km in elevation, is linked to deep-Earth processes that can explain short-lived, extreme rates of topographic change.
The Many Magmatic Modifications to the African Continent
How the very slow moving African Continent, with a lithosphere of quite varied age elements and thickness, has responded to ongoing asthenospheric modification.
Seafloor Activity Sheds Light on Plate Tectonics
Scientists in Japan study stress released by oceanic earthquakes in newborn sections of seafloor.
Measuring Earth’s Elasticity
A new study illuminates how crustal rocks break and stretch.
Unraveling the History of the India-Asia Collision
A study of deformed and metamorphosed rocks exposed in Tibet’s Lopu Range suggests that episodes of crustal shortening and extension during the evolution of the Himalaya are related to subduction processes.
Reinterpreting the Age and Origins of Taiwan’s Yuli Belt Terrane
Uranium-lead dating of zircons from Taiwan’s east central metamorphic belt offers robust evidence that this uplifted terrane is some 90 million years younger than previously thought.
On the Origin of Low-Angle Detachment Faults
Data from California's Whipple Mountains suggest this complex was formed by a succession of steep normal faults, challenging the paradigm that detachments are different types of faults.
