Nanolite ‘snow’ surrounding an iron oxide microlite ‘Christmas tree’. Even these small 50 nm spheres are actually made up of even smaller nanolites aggregated into clumps. Christmas has come early this year for these researchers. Credit: Brooker/Griffiths/Heard/Cherns In a new study of volcanic processes, Bristol scientists have demonstrated the role […]

Archaeologic excavations at Hall’s Cave exposed sediments for geochemical analysis that span from circa 20,000 to 6,000 years. Credit: Michael Waters, Texas A&M University Researchers say cooling 13,000 years ago is coincident with major volcanic eruption. Texas researchers from the University of Houston, Baylor University and Texas A&M University have […]

They might share the same name, but ash produced in the western wildfires is a very different hazard than ash produced in explosive eruptions.

Bezymianny is an active stratovolcano on the Kamchatka peninsula in eastern Russia. Credit: GFZ For the first time, long-term photogrammetic series document the “life cycle” of a volcano. The analyses shows that volcanoes have a kind of memory. Volcanoes are born and die — and then grow again on their […]

Three water-filled maars in the Eifel, Germany (Gemündener Maar, Weinfelder Maar, Schalkenmehrener Maar). Created by volcanic activity, maars are also found in other parts of Europe and on other continents, but Eifel-Maars are the classic example worldwide.

The 2015 eruption at Wolf volcano in the Galapagos Archipelago. Credit: Gabriel Salazar, La Pinta Yacht Expedition. An international team of volcanologists working on remote islands in the Galápagos Archipelago has found that volcanoes which reliably produce small basaltic lava eruptions hide chemically diverse magmas in their underground plumbing systems—including […]

Venus is the second planet from the Sun. Credit: NASA ETH researchers used computer simulations to classify the current activity of corona structures on the surface of Venus. To their surprise, they found a previously undiscovered ring of fire on our neighboring planet. Years ago, planetary researchers discovered unusual circular structures […]

Animation New 3D model provides evidence that Venus is churning inside. A new study identified 37 recently active volcanic structures on Venus. The study provides some of the best evidence yet that Venus is still a geologically active planet. A research paper on the work, which was conducted by researchers at the […]
