A diagrammatic representation of the Earth in the Archaean showing subducted ocean floor carrying its chemical signature into the deep mantle. The signature which includes water and chlorine is preserved in melt inclusions contained within olivine and carried back up to surface within komatiite lava flows.

Scientists uncover deep-rooted plumbing system beneath ocean volcanoes

Multiple volcanic craters cover the 'Campi Flegrei' near Naples, Italy. A new method aims at forecasting where new vents will occur.

How to recognise where a volcano will erupt

Pressure changes in the summit reservoirs of Kīlauea may help explain the number of earthquakes — or seismicity — in the volcano’s upper East Rift Zone.

Tamu Massif made news in 2013, thought to be the world's largest volcano. New research offers a better look at the volcano's formation and throws doubt on that claim.
