Numerical simulations of earthquake cycle deformation reveal that co-seismic and interseismic fault propagation can produce distinct propagation angles that may be recorded in the crust.Read More »Geology & Geophysics
A laboratory study assesses thermochemical remanence as a reliable paleointensity recorder, which could open new venues for studying Earth’s ancient magnetic field.Read More »Geology & Geophysics
A high-resolution map of surface displacements indicates that the 2017 Chiapas earthquake caused substantial creep along a segment of the San Andreas Fault, located 3,000 kilometers away.Read More »Geochemistry, Mineralogy, Volcanology
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
