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.

An Integrated History of the Australian-Antarctic Basin
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.
Laboratory Study Probes Triggering Mechanisms of Earthquakes
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.
Variations in Creep Along One of Earth’s Most Active Faults
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.
Déjà Vu: Understanding Subduction Zones’ Cycle of Seismicity
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.
X-Ray Computed Tomography Detects Resolution Scale Gold Grains
A method combining partial-volume and blurring effects can be used to measure small features in computed tomography data volumes.
A New Way of Visualizing Iceland’s Crustal Deformation
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.
All Types of Large Earthquakes Produce Prompt Gravity Signals
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.
Extraordinary Polar Wander During the Late Jurassic?
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?
New Global Crustal Model Built as Foundation for Future Studies
A new global crustal model and its corresponding uncertainty were obtained using minimum a priori information and a geostatistical approach.
