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 ...

Scientists have long wondered how volcanoes formed in central Anatolia despite being far from tectonic plate borders—now they've found evidence of a hot plume of magma flowing from East Africa. Riders ...

New research reveals the source of this carbon – and the driving forces behind it – are far more complex than previously ...

The magma that erupts from basaltic volcanoes in the middle of tectonic plates originates from within Earth's mantle — rather than from the outer crust — and is propelled upward by CO2, not water.

For most of deep time, spreading ridges released more carbon than volcano chains, changing how we interpret Earth’s climate history.

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Deep below the Earth's surface, magma is churning and flowing into the Axial Seamount, an underwater shield volcano about 300 miles off the coast of Oregon. As the volcano grows and tremors increase, ...

Researchers have examined tiny time capsules found in the oldest-known crystals in an attempt to settle a question that divides scientists: when did Earth’s tectonic plates begin to move? Plate ...

Natural disasters, from wildfires, floods and mudslides in western states to large earthquakes in Japan, have rocked, burned and flooded parts of the world in the first months of 2025. What’s next?
