Fluid inclusions in volcanoes are dominantly composed of carbon dioxide. At magmatic temperatures — 2,192 degrees — the density of the carbon dioxide strongly depends on pressure, which is influenced ...

A new study based on the sampling and analysis of volcanic ash at Cumbre Vieja volcano in the Canary Islands, located off Africa's northwest coast, suggests that the composition of magma could drive ...

A massive, iron-rich structure sitting at the base of Earth’s mantle beneath the Hawaiian Islands may be doing more than ...

Scientists have collaborated to analyze the inner workings of Bolivia's 'zombie' volcano, Uturuncu. By combining seismology, physics models and analysis of rock composition, researchers identify the ...

Learn how a young volcano on Mars stayed active for nine million years and what its changing lava reveals about Mars’ interior.

Volcanic activity from Etna's 'Voragine' crater has intensified this week with vigorous explosions and incandescent shreds following a four-year silence. Etna and Stromboli are the most explosive ...

The Durandag mud volcano, known for its periodic activity, entered a new eruption phase, producing a powerful outburst that ...

Volcanoes may look like simple mountains that erupted once and then fell silent, but in reality they are often the surface expression of complex processes happening deep underground. Magma can move, ...
