Scientists reveal how the behavior of gases inside magma chambers could trigger the eruption of major volcanoes.

Kilauea is one of the most active volcanoes in the world with eruptions common both at its summit caldera and within its two rift zones. Frequent earthquakes associated with volcanic activity can help ...

How do volcanoes work? What happens beneath their surface? What causes the vibrations—known as tremor—that occur when magma or gases move upward through a volcano's conduits? Professor Dr. Miriam ...

Fresh modeling reconstructing the evolution of a magma dike pushing up through the Earth's crust underneath Iceland suggests that it "could be wider than initially assessed" and therefore could pose a ...

Understanding what triggers large volcanic eruptions is crucial for hazard assessment, but the exact mechanism driving these ...

Around the world, volcanologists are following the path of magma as it travels between connected volcanoes, in an effort that ...

Researchers traced tremor signals deep inside Tanzania’s Oldoinyo Lengai volcano, pinpointing their 3D locations for the first time. The study revealed linked tremors at different depths, offering a ...

A Martian volcano once thought to be the result of a single eruption turns out to have a much more complex past. Orbital imaging and mineral data show it developed through multiple eruptive phases, ...

Scientists reveal a hidden magma and fluid system beneath Ebeko volcano, explaining how quiet surfaces can lead to sudden ...

Iceland offers some of the Earth's most dramatic sights. And if you head off the beaten path, you can explore some of its lesser-known attractions from ice caves to bubbling lava fields and silent ...

A volcanic formation known as Pele’s hair is produced when air-filled magma is stretched, according to a new study by a team ...
