The Ridgecrest Earthquake Left Enduring Damage in Earth’s Deep Crust
The shallow crust has recovered since California’s 2019 quake, but damage persists at depths greater than 10 kilometers.
AI is Changing our Understanding of Earthquakes
Machine learning is expanding scientists’ catalogs of quakes and refining maps of underground faults. It also promises to improve quake forecasts.
New Earthquake Model Goes Against the Grain
Subducting plates are stronger in certain directions than others, which may be a factor in how earthquakes occur and how seismic waves propagate.
When the Earth Moves: 25 Years of Probabilistic Fault Displacement Hazards
Surface ruptures causing earthquakes pose risks to infrastructure and human lives, but advances in models and data in the last few decades have improved our ability to mitigate their effects.
Scientists Tune In to the Ocean’s Sound Waves
A new technique detects inaudible acoustic signals from crashing waves, opening up possibilities for monitoring sea and atmospheric conditions from shore.
Scientists May Have Finally Detected a Solid Inner Core on Mars
Seismic clues from NASA’s InSight mission suggest that Mars hides a solid inner core, and raise new questions about why the planet’s magnetic field disappeared.
Unexpected Carbonate Phase Revealed by Advanced Simulations
Advanced simulations reveal a new calcium carbonate phase whose unusual elastic behavior may explain puzzling seismic and electrical anomalies beneath ancient continents.
New Perspectives on Energy Sinks During Seismic Events
Laboratory earthquakes shed new light on energy partitioning during earthquakes, which is allocated to seismic radiation, creation of new surfaces, and heat dissipation.
Scientists Track Down Fresh Boulder Falls on the Moon
By poring over thousands of satellite images, researchers geolocated 245 fresh boulder tracks, revealing signs of seismic activity or impact events within the last half-million years.
