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” ...

An underwater volcano off the coast of Oregon could now blow its top by mid-to late-2026, scientists say. In December last year, scientists said the Axial Seamount was nearing the threshold seen ...

HONOLULU (AP) — Lava shoots high into the sky. Molten rock erupts from two vents simultaneously. The nighttime sky glows red and orange, reflecting the lava oozing across a summit crater. Scientists ...

Although researchers did predict the Axial Seamount would erupt in 2025, people on the Pacific coast shouldn't worry about its impact. Axial's eruptions are akin to the ones in Hawaii in which runny ...

Scientists are closely monitoring Axial Seamount, a submarine volcano located about 300 miles west of Oregon in the Pacific Ocean. Recent data show that this volcano is inflating, or “ballooning,” due ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. How and if a volcano explodes depends on how and when bubbles of ...
