When volcanoes like Alaska’s Mount Spurr erupt, the ash can damage people’s lungs, smother crops and kill animals, and the harm can continue to spread long afterward.

A newly discovered half-million-year-old layer of volcanic sediment beneath the Aegean Sea rewrites what scientists know about this area’s volcanic history – and potential future hazards.

Iceland, Hawaii and Italy have all tried to control lava to save cities in the past. A volcanologist explains the methods.

Iceland is known as ‘the land of fire and ice’ for a reason.

Iceland’s volcanic activity is generally tame compared with explosive eruptions along the Pacific’s Ring of Fire. This time, it’s shaking up a town.

Evidence suggests magma is close to the surface in south-west Iceland, prompting evacuations.

Scientists were not previously certain how the precious stones arrived at the Earth’s surface.

As they shape the Earth, volcanoes inspire and terrify humans.

A scientist who led one of the first projects to map the Hawaiian Islands’ deep volcanic plumbing explains what’s going on under the surface as Mauna Loa erupts.
