How volcanoes form and erupt - explained by geologists
Where Volcanoes Are Born Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and ...
Recent laboratory and modeling work argues that a hidden instability in this gas–magma mixture can suddenly tip a seemingly steady system into an explosive regime, revealing a physical trigger that ...
The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped ...
About 290 miles off the coast of Cannon Beach, Oregon, lies an underwater volcano called Axial Volcano. Axial erupts about once every ten years. Twice in the past year, news outlets have reported that ...
UNIVERSITY PARK, Pa. — For people living near volcanoes, danger goes well beyond lava flows and clouds of ash. Some explosive eruptions can lead to dramatic collapses of the sides of a volcano, like ...
Researchers at Diamond Light Source have used advanced imaging to look at microscopic crystals, called nanolites, to see what they can tell us about volcanic eruptions. Highly explosive eruptions ...
Dick Fiske, who died on June 18 as he neared his 93rd birthday, was one of the most original thinkers ever at the USGS Hawaiian Volcano Observatory. His ideas, interpretations, and concepts underlie ...
