Molecular dynamics calculations suggest that molten hydrogen-bearing iron peroxide (FeO2Hx) may produce the ultra-low velocity zones that occur at the core-mantle boundary.Read More »Natural Hazards
Granular flows are important in geophysics to the pyroclastic flow, debris flow, and avalanches. Understanding their complex and rich physics is therefore important in simulating their dynamics.Read More »Geology & Geophysics
The first basin-wide compilation of seismic and geologic data shows that both margins experienced similar sedimentation patterns prior to the onset of Antarctic glaciation.Read More »Geology & Geophysics
A new experimental technique traces the state of a shearing fault gouge and shows for the first time how friction of a fault surface can change as a function of varying normal stress.Read More »Geology & Geophysics
Satellite-based radar images of motion along Turkey’s North Anatolian Fault are helping scientists understand when, where, and how creep occurs and its implications for seismic hazard.Read More »Geology & Geophysics
A unique geodetic data set from Japan’s Nankai subduction zone offers an unparalleled opportunity to study surface deformation spanning almost an entire seismic cycle.Read More »Mathematical Geophysics
A method combining partial-volume and blurring effects can be used to measure small features in computed tomography data volumes. Read More »Geology & Geophysics
A novel method of calculating strain rates from GPS data shows the South Iceland Seismic Zone is experiencing rapid deformation, including inflation near the island’s most active volcano.Read More »Geology & Geophysics
New observations of recently discovered gravity perturbations that precede seismic waves have the potential to improve earthquake early-warning systems in California and other tectonic settings.Read More »Geology & Geophysics
Small amounts of polar wander have occurred during geological history, but whether larger amounts occurred is still controversial. Did a truly large polar wander event really happen?Read More »
