Deflected Dikes Perturb the Plumbing System
A multidisciplinary synthesis of the Campi Flegrei, Italy volcanic setting highlights the importance of sub-caldera layering for magma dynamics.
Martian Magmas Live Long and Prosper
The depths, longevity, and potential to generate silicic compositions of magma chambers are linked to crustal temperature, which varies across Mars and over its geological history.
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.
Come on Feel the Noise: Machine Learning for Seismic-Wind Mapping on Mars
Wind vibrations measured by NASA’s InSight mission seismometer are mapped into wind speed and direction to detect major annual weather patterns and open new possibilities for planetary instrumentation.
Seismometers Provide Fuller Picture of Los Angeles Groundwater
A new method to evaluate deep aquifers shows even torrential rains haven’t fully replenished groundwater beneath Los Angeles.
Listening to Groundwater Dynamics
Deep learning from shallow passive seismic data reveals groundwater table depth information in space and time.
Tiny Icequakes Ripple Through Greenland’s Largest Ice Stream
Seismologists made an accidental discovery on the Northeast Greenland Ice Stream, changing the way glaciologists understand how ice moves.
