Volcanic Tremor and Deformation at Kīlauea
Two new studies investigate activity at Hawaii’s Kīlauea leading up to and following the 2018 eruption to better understand the volcano’s plumbing and behavior.
Understanding and Anticipating Induced Seismicity
A new special collection in JGR: Solid Earth and Earth and Space Science seeks papers from across disciplines that provide insights into induced seismicity at different spatial and temporal scales.
Crustal Motion and Strain Rates in the Southern Basin and Range Province
New research teases out variations in strain rates and explores potential earthquake hazards across the southern Basin and Range and Colorado Plateau.
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.
