Peering into “calm” volcanoes that hide explosive potential One of the most striking implications of the new research is that volcanoes that look placid at the surface can still harbor highly ...

Melting glaciers may be setting the stage for more frequent and explosive volcanic eruptions in the future. This is the conclusion of a study of six volcanoes in the Chilean Andes, which is being ...

When individuals hear volcanoes, they tend to envision blazing eruptions blasting into the air. However, volcanoes can also collapse sideways, with their sides, or flanks, collapsing. Such a collapse ...

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 ...

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 ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” ...
