Splash saves Dunk before the volcano erupts. Splash saves Dunk before the volcano erupts. The magma from a volcano comes all the way from the earth’s core. When eruption, the magma, or molten rock, ...

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 ...

For decades, volcanologists believed that the primary trigger for explosive eruptions was a drop in pressure as magma rises toward the surface. When pressure falls, gases dissolved deep within the ...

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” ...

Learn how stress inside a volcano can make gas bubbles form early, helping explain why some eruptions stay quiet instead of exploding. Anastasia Scott is an Editorial Assistant at Discover Magazine.

In a new study, researchers show that gas bubbles can form in the rising magma not only due to a drop in pressure but also due to shear forces. If these gas bubbles grow in the volcanic vent early on ...
