Volcanoes can behave in strikingly different ways, even when they appear nearly identical. Some release slow, steady lava ...

Volcanoes often look deceptively quiet until the moment they unleash towering plumes of ash and gas, yet the precise switch that turns a gentle rumble into a devastating blast has remained stubbornly ...

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 ...

Melting glaciers may be silently setting the stage for more explosive and frequent volcanic eruptions in the future, according to research on six volcanoes in the Chilean Andes. A study to be ...

Researchers found that a magma's thermal history may be a key factor in determining whether an eruption becomes more vigorous ...

Volcanic soils, covering only ~1% of the Earth’s land, store over 5% of the global soil organic C stock. The frequent burial of these soils by tephra fallout from explosive volcanic eruptions is a ...

It is generally assumed that volatile-rich magmas erupt predominantly effusively at water depths of several hundred meters, as the high hydrostatic pressure suppresses explosive activity. This view is ...

Learn about how volcanoes are formed and the ways they erupt Chiara Maria Petrone, Roberto Scandone, and Alex Whittaker On February 20, 1943, Dionisio Pulido and his family were working in their ...

He joked that, when the experiments were over, his kids could eat the volcanoes. While at the Smithsonian, Dick enabled museum exhibits celebrating HVO’s 75th anniversary in 1987 and arranged for ...
