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” ...

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 ...

Learn how stress inside a volcano can make gas bubbles form early, helping explain why some eruptions stay quiet instead of exploding. One of the most explosive volcanoes in U.S. history began its ...

Learn more about the connection between melting glaciers and volcanic eruptions, a volatile relationship that has existed since the last Ice Age. Over the last few decades, melting glaciers and ...

Over the last few decades, melting glaciers and erupting volcanoes are two events that have captured the attention of scientists and the general public alike. But have you ever thought about how these ...
