Mount Etna draws magma from a deep reservoir 50 miles underground, reshaping how scientists understand its eruptions and ...

A seamount sitting on a subducting tectonic plate off the coast of Japan and plowing its way into Earth's mantle may be at the root of several magnitude 7 earthquakes in the past 40 years. When you ...

Located in Sicily, Mount Etna is Europe's most active volcano. Yet its origin remains largely enigmatic, as no existing ...

Learn how Mount Etna stands apart from most volcanoes, having been formed by pockets of magma held in Earth's upper mantle.

Understanding this link helps scientists predict where volcanoes and earthquakes are likely to occur. It also helps explain how continents slowly pull apart and form new oceans. Over time, the Afar ...

A new model of Yellowstone’s magma system suggests it is fueled by melts from the shallow mantle, guided by tectonic forces, ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science ...

Along 1,100 kilometers, from Mexico to Costa Rica, lies the Central American volcanic arc, where the variety of magma types make for a geological paradise. By Pablo Fonseca Q. / Knowable Magazine ...

Volcanoes are Earth’s geologic architects. They’ve created more than 80 percent of our planet’s surface, laying the foundation that has allowed life to thrive. Their explosive force crafts mountains ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

Carbon released from Earth’s spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ice ages and warm climates, new research finds. Published today in ...
