Unmixing Magnetic Components – An Experimental Twist
Various unmixing approaches are used in environmental magnetism, each starting from a different premise; now they are put to the test by scrutinizing experimental mixtures of known endmembers.
Eruption Seismic Tremor Modeled as a Fluvial Process
Impact and turbulence models for river tremor are adapted and combined into a model that predicts the amplitude and frequency content of volcanic eruption tremor.
Southern California’s Crustal Motion Tells of Earthquake Hazards
Precise measurements of the Earth’s vertical surface motion help to elucidate the hazards of faults in an earthquake-prone region.
Radon Enrichment in the Volcanic Plume of Mount Etna
More than 70 passive sensors on Mount Etna have captured the first radon measurements in volcanic plumes and show that radon could affect people around volcanoes.
The Restless Geomagnetic Field Over the Past 70,000 Years
Detailed paleomagnetic records from Black Sea sediments reveal intricate changes in the field during geomagnetic excursions.
Steadying Mid-Ocean Ridge Spreading Rates
Researchers used an up-to-date global magnetic anomaly data set to track the history of magnetic field reversals and obtain more accurate estimates of tectonic spreading rates.
Strain Rate: The Overlooked Control on Earthquake Depth
Regional strain rate may play as significant a role as temperature in governing the depth distribution of earthquakes in mantle lithosphere.
Unexpected Oceanic Lithosphere-Asthenosphere P-wave Velocities
A peak in seismic P-wave – S-wave velocity ratios at the lithosphere-asthenosphere boundary beneath old Pacific lithosphere requires an additional property besides temperature as an explanation.
