Learn how stress inside a volcano can make gas bubbles form early, helping explain why some eruptions stay quiet instead of exploding.

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” ...

For decades, volcanologists believed that the primary trigger for explosive eruptions was a drop in pressure as magma rises ...

An active underwater volcano 300 miles off the Oregon Coast that was predicted to erupt in 2025 is now expected to erupt ...

Watch an exciting chemical reaction between an acid and a base create a volcanic eruption! This classic experiment teaches about chemical reactions, gases, and pressure while creating an impressive ...

An underwater volcano off Oregon's coast is likely to erupt in 2025, according to scientists monitoring the situation. Axial Seamount—the most active volcano in the northeast Pacific Ocean—is located ...

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 ...
