A small international team of volcanologists has built a more detailed picture of the Campi Flegrei caldera’s internal structure using high-resolution seismic imaging and results from rock physics experiments conducted on core samples collected from […]

A newly published study finds that California’s Salton Sea emits hydrogen sulfide, a toxic and foul-smelling gas, at rates that regularly exceed the state’s air quality standards. The presence of these emissions in communities surrounding […]

A study co-led by Irina Gorodetskaya, a researcher at the Interdisciplinary Center of Marine and Environmental Research (CIIMAR), brings together all up-to-date data on the phenomenon of atmospheric rivers in Antarctica and reveals the uncertainties […]

New research led by the University of Sydney adds to our understanding of how rapidly rising sea levels due to climate change foreshadow the end of the Great Barrier Reef as we know it.This post […]

North America’s deepest gorge, Hells Canyon, which slithers along the border of Idaho and Oregon, is a surprisingly new addition to the Earth’s ancient landscape. A recent study suggests that a monumental shift in Snake […]
