New Insights into How Rocks Behave Under Stress
New 3D imaging techniques show hidden patterns of stress that help explain how and why rocks break.
Creep Cavitation May Lead to Earthquake Nucleation
Ultramylonites, rocks of ultrafine grainsize, bring records of nanometer-scale cavities generated at the base of seismogenic crust along Japan’s largest on‐land fault.
Atomic-Scale Insights into Supercritical Silicate Fluids
Water-induced depolymerization enhances fluid mobility in deep Earth, offering new insights into magma transport and isotope signatures in arc lavas.
Seismic Images Show Major Change Along the Mid-Atlantic Ridge
New seismic images of the Lucky Strike slow-spreading segment of the Mid-Atlantic Ridge show thick lower crust at the center that thins in both along-ridge directions.
Remagnetization Illuminates Tectonic Consolidation of Megacontinents
New rock and paleomagnetic research give evidence for prolonged heating during the Cambrian-Ordovician tectonic consolidation of West Gondwanaland.
T-waves May Improve Tsunami Early Warning Systems
A unique acoustic wave related to the generation of tsunamis could be used to enhance early warning systems.
Slow But Powerful Fault Slip Can Simply Arise from Fluid Flow
Cyclic changes of fluid pressure in fault zones can induce slow-slip events that advance in the direction of fluid flow, even when the faults are stable.
Rewinding the Fault: Stress Perturbations Promote Back-Propagating Ruptures
Free surface reflection and fault geometric asperities can excite backward propagation in the form of an interface wave or high-order re-rupture.
Diverse Seismic Response in Hectometer-Scale Fracture System
An underground experiment with multi-stage stimulations reveals diverse seismic responses within a complex hectometer-scale fracture network, shedding light on induced seismicity behaviors at field scale.
