Volcanoes across the country are beginning to wake up and erupt, and no one has a good explanation for why it's happening.

Earth's continents may look fixed on a globe, but they've been drifting, splitting and reforming over billions of years—and they still are. Our new study reveals fresh evidence of rhythmic pulses of ...

As magma stirs beneath the surface, a notorious Icelandic volcano threatens to awaken once more, sending ripples of fear through nearby towns and retreats.

Learn about how volcanoes are formed and the ways they erupt Chiara Maria Petrone, Roberto Scandone, and Alex Whittaker On February 20, 1943, Dionisio Pulido and his family were working in their ...

Japan's 122 volcanoes qualify it as a hotspot along the Pacific Ring of Fire. As tectonic plates converge under the islands, the nation is prone to frequent earthquakes. Landmark volcanoes like ...

Global Thaw 10,000 Years Ago May Have Fueled Volcanoes and Sped Up Continental Drift Learn how a computer simulation demonstrates that tectonic activity may be less slow and steady than previously ...

Mantle plumes can stay fixed in place for millions of years while tectonic plates move slowly above them. As a plate drifts, the plume continues to produce volcanoes, which form a chain of islands.

Scientists have worked for years to build better systems to keep people safe from earthquakes and volcanoes. Will those systems survive?

For many years, scientists have believed that the Earth’s mantle – the layer beneath its surface – moves like a giant conveyor belt, carrying heat and material that form volcanoes. But new ...
