Previous Intra-oceanic Subduction Found Beneath South America?
Newly mapped fast velocity slabs in the lower mantle may be remnants of westward dipping intra-oceanic subduction, before flipping to the present eastward subduction beneath South America at 85 Ma.
Revealing Complexity of Groundwater Flow with Hydrogeophysics
A combination of passive seismic and electrical measurements are used to unravel the complex hydrogeology structure and associated groundwater flow paths at a coastal site in O’ahu, Hawai`i.
When Will the Next Failure Be?
Unprecedented images of fracture networks in laboratory scale experiments mixed with machine learning algorithms help predict the timing of the next failure.
Geologists to Shed Light on the Mantle with 3D Model
The model, which will incorporate 227 million surface wave measurements, could help with everything from earthquake characterization to neutrino geosciences.
The Resurrection Plate Is Dead, Long Live the Resurrection Plate
Using a technique similar to taking a CT scan of Earth, researchers found the possible remnants of a long-debated “missing” tectonic plate.
Earthquake-coda Tomography Boosts Illumination of the Deep Earth
A new tomographic method based on correlations of seemingly chaotic earthquake coda waves yields otherwise unobservable arrivals, thus greatly improving illumination of the deep Earth.
CAT Pictures of Internal Solitary Waves in Indonesian Strait
Huge and rapid subsurface temperature changes associated with propagating internal solitary waves were observed from a moored coastal acoustic tomography (CAT) system in Lombok Strait in Indonesia.
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.
The Unsolved Mystery of the Earth Blobs
Researchers peering into Earth’s interior found two continent-sized structures that upend our picture of the mantle. What could their existence mean for us back on Earth’s surface?
