Observing Volcanoes from Space
The first multidecadal, satellite-based study of Latin America’s most active volcanoes could help researchers better predict eruptions.
Real Time Probing of Shale Cracks in Double Torsion Experiments
Imaging crack propagation in shales using twin optical cameras and fast X-ray radiograph acquisition.
Ancient Faults Amplify Intraplate Earthquakes
A comparison of deformation rates from Canada’s Saint Lawrence Valley offers compelling evidence that strain in the region is concentrated along ancient structures from previous tectonic cycles.
Unraveling the Origin of Slow Earthquakes
Different nucleation styles detected in five slow-slip events in the same area of Japan’s Ryukyu subduction zone suggest the physical properties along this tectonic plate interface change over time.
New Method to Measure Ice Cap Thickness
Naturally generated seismic waves bouncing up and down through an ice sheet can be used to determine the thickness of the ice and monitor future changes in ice thickness.
Unraveling the Origins of Australia’s Ancient Mountain Chains
New data synthesis suggests that varying rates of trench retreat along the margin of the Gondwana supercontinent were responsible for the curvature of the Tasmanide mountain chains.
Removing the Drudgery from Earthquake Seismology
New methods of machine learning are bringing the phase arrival time and polarity picking used for automatic determination of earthquake fault planes to accuracies better than human analysists.
Basement Structure Mapped by Phase Autocorrelations of Noise
Cross-correlations of ambient seismic noise are combined with well log data to image shallow crustal basement features in the Ebro Basin in Spain.
Linking Mantle Plumes to Volcanoes and Hot Spot Tracks
Study bolsters hypothesis that volcanoes on China’s Hainan Island were formed by a hot spot.
