Seismic tools reveal where hydrothermal fluids lie beneath the Uturuncu volcano in Bolivia and hint at their composition.
Observing a Seismic Cycle at Sea
Scientists organized a trio of expeditions to document the buildup of stress leading to a large earthquake on a seafloor fault, developing innovations for successful seagoing research in the process.
Accounting for Offbeat Earthquakes Could Improve Forecasts
A new model considers the full history of earthquakes on a fault, improving forecasts of when the next will strike.
Crystals Track Magma Movement Beneath Iceland
Crystals from Fagradalsfjall’s eruption mark how mantle magma might have been moving years before geophysical indicators alerted scientists to unrest.
New Tectonic Plate Model Could Improve Earthquake Risk Assessment
A new model of tectonic plates in New Zealand may identify areas of increased earthquake likelihood.
Meteor Impact Could Inform Martian Mysteries
The impact sent surface waves rippling over the Martian surface all the way to NASA’s InSight lander, giving scientists a rare view of the planet’s outer layer.
Enhancing Earthquake Detection from Orbit
A new application of machine learning boosts scientists’ ability to use data from satellite navigation systems to detect and warn of earthquakes.
Powerful Impact Provides Insight into Deep Structure of Mars
Seismic signals detected by the InSight lander show that the planet’s lower mantle may be less homogenous than previous models have suggested.
Reaching New Levels in Groundwater Monitoring
As regions around the world face record-breaking droughts, researchers are using seismology to track groundwater levels and show that sustainable policies reduce strain on aquifers.
