Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and upper mantle that fit together like puzzle pieces. Think of these plates as massive rafts floating ...

Learn how magma, gas, and water drive eruptions; compare eruption and volcano types, understand warning signs, and follow ...

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, ...

Learn how stress inside a volcano can make gas bubbles form early, helping explain why some eruptions stay quiet instead of exploding. One of the most explosive volcanoes in U.S. history began its ...

For more than 100,000 years, a Greek volcano lay silent. But deep underground, it was still growing. Tiny zircon crystals show magma was quietly brewing between eruptions, researchers report April 22 ...

Scientists have shed light on a thermal process in magma that may help explain why similar volcanic systems can produce very different eruptive behaviours. An international team, led by The University ...

Since early May, an undersea volcano has been erupting in the Bismarck Sea, along a feature that scientists call the Titan Ridge. It’s in the southwestern Pacific Ocean, just off the north coast of ...
