High-precision airborne measurements, in combination with atmospheric modeling, suggest that the Katla subglacial caldera may be one of the planet’s biggest sources of volcanic carbon dioxide.Read More »
The amount of CO2 segregated from the mantle by carbonate melting beneath old oceanic crust may equal that emitted along the mid-ocean ridge system, thereby contributing to the global carbon cycle. Read More »Geochemistry, Mineralogy, Volcanology
Volcanologists say it’s too soon to know whether the sudden drop in activity signals the end of the eruption or just a pause.Read More »Geology & Geophysics
Although rare at the Earth’s surface, diamonds may be commonplace at depths of 120 to 150 kilometers below the surface within the lithosphere of old continents.Read More »Geochemistry, Mineralogy, Volcanology
Evidence collected following the 2011 eruption of Japan’s Shinmoedake volcano suggests that the powerful event affected the behavior of an active caldera nearby.Read More »
