Deep under the Pacific Ocean, more than 300 miles off the Oregon coast, lies a restless underwater volcano known as Axial ...

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” ...

Scientists have discovered that shear forces inside rising magma can create gas bubbles long before pressure drops occur. The intensity of a volcanic eruption is shaped by how many gas bubbles develop ...

Far off the Oregon Coast, a restless underwater volcano has been rattling the seafloor with swarms of tiny earthquakes, ...

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 ...

Mount Semeru erupted again today, its 7th time this week, reaching Level III (Alert). PVMBG warns against activity near Besuk ...

HONOLULU — Hawaii's Kilauea volcano resumed erupting Friday by shooting an arc of lava 100 feet (30 meters) into the air and across a section of its summit crater floor. It was Kilauea's 31st display ...

Mount Semeru erupted again on Dec 8, 2025, reaching Level III (Alert). It had 41 eruption earthquakes. PVMBG warns against ...
