Lava flowing across black rocks. International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the world’s most continuously active — erupting for 30 million years — fueled by a constantly moving ‘conveyor belt’ of magma. It’s believed this magma ‘conveyor […]

(l-r) Jonny Wu, assistant professor of geology in the UH Department of Earth and Atmospheric Sciences and Spencer Fuston, a third-year geology doctoral student, applied a technique developed by the UH Center for Tectonics and Tomography called slab unfolding to reconstruct what tectonic plates in the Pacific Ocean looked like […]

An artist’s rendering of undersea earthquake waves.

The method, which they tested in the East Indian Ocean and where they uncovered a decadal […]

Central Alps of Switzerland have been lifted to today’s height. Credit: ETH Zurich ETH researchers have used a computer model to test a new hypothesis about the formation of the Alps while simulating seismic activity in Switzerland. This will help improve current earthquake risk models. For a long time, geoscientists […]

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 […]

For that reason, monitoring […]

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 […]

Rock-melting forces occurring much deeper in the Earth than previously understood appear to drive tremors along a notorious segment of California’s San Andreas Fault, according to new USC research that helps explain how quakes happen. The study from the emergent field of earthquake physics looks at temblor mechanics from the bottom up, […]

Reconstructed image of the fracture zone. Credit: Hicks et al. Scientists observed a ‘boomerang’ earthquake along Atlantic Ocean fault line, providing clues about how they could cause devastation on land. Earthquakes occur when rocks suddenly break on a fault – a boundary between two blocks or plates. During large earthquakes, […]
