New high-pressure experiments on fluid iron suggest thermal convection without compositional buoyancy is sufficient to drive the dynamo generating Earth’s magnetic field.Read More »Geochemistry, Mineralogy, Volcanology
Researchers used a combination of ground and space-based measures to look for warning signs for the flank collapse at Anak Krakatau in 2018, which triggered a tsunami that killed hundreds.Read More »Geochemistry, Mineralogy, Volcanology
Temperature fluctuations, maybe from climate or maybe from geothermal systems, amplified a natural process that grew the crystals.Read More »Biogeosciences
In October, we celebrate AGU’s Centennial by looking under our feet, where the relatively new study of plate tectonics is evolving rapidly.Read More »Geohealth
Little seismic unrest preceded the 2014 eruption of a stratovolcano in Indonesia, which suggests that the eruption was kick-started internally by volatile-triggered overpressure.Read More »Geochemistry, Mineralogy, Volcanology
