A New Method Produces Improved Surface Strain Rate Maps
The transdimensional Bayesian approach handles GPS data limitations better than existing methods and may assist future seismic hazard assessment studies.
Reconstructing Rocks with Machine Learning
Machine learning can be used to accurately reconstruct high-resolution, 3D images of rocks from 2D cross-sections, which opens the door to more detailed simulations.
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.
Improved Seismic Imaging Via Optimal Transport Theory
Seismic waveform inversion is inherently non-linear. New objective functions based on optimal transport theory mitigate nonlinearity yielding stable solutions without need for accurate initial models.
Magma Pockets Lie Stacked Beneath Juan de Fuca Ridge
Analysis of new imaging data suggests that vertically stacked magma chambers are short-lived and contribute to eruptions.
A New Approach to Calculate Earthquake Slip Distributions
A transdimensional, probabilistic approach is more flexible than traditional least squares fits and provides better handling of sharply varying slip distributions.
A Comprehensive Review of Submarine Volcano Seismoacoustics
Although most of Earth’s lava erupts beneath the oceans, submarine volcanoes are comparatively understudied, but a new review of submarine volcano seismoacoustics provides a framework for future work.
Understanding Where and How Magma is Stored
Gravity measurements reveal depth and storage conditions of rhyolitic magma reservoirs beneath the Laguna del Maule volcanic field in Chile.
New Spherical Cap Field Model for Europe and Direct Environs
New data on ancient burnt structures is integrated into a superior spherical cap field model for Europe.
