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” ...

Volcanoes are often framed as nature’s most violent spectacles, yet some of the largest on Earth ooze lava quietly for years without a single dramatic blast. Scientists have now pulled together a ...

An active underwater volcano off the Oregon Coast that was predicted to erupt in 2025 is now expected to erupt mid-to-late 2026. The Axial Seamount volcano is located nearly a mile beneath the sea, ...

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 ...

Volcanoes erupt because hot, melted rock from deep inside the Earth finds a way to reach the surface. This melted rock is called magma, and it forms when parts of the Earth’s mantle become so hot that ...

Visual observations have been a backbone of volcano research more than 2,000 years and remain fundamental to understanding ...

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 ...

One of the most active volcanoes in the world is living up to its reputation as it gears up for another eruption. An eruption at Hawaii's Kilauea volcano is imminent, based on current activity, ...
