New research shows that satellite measurements of tiny movements of the Earth's surface can tell scientists what is happening in the deeper layers of our planet.
Mercury found in prehistoric rock bolsters the idea that volcanoes caused a mass extinction 200m years ago.
Melting ice from Antartica could feed vast plankton blooms, trapping carbon in the ocean. To understand this complex mechanism, researchers looked at volcanoes deep under glaciers.
The planet is more similar to Earth than any other – except when it comes to supporting life.
The Noril’sk nickel deposits In Russia are unique: giant volcanic eruptions 250 million years ago released colossal amounts of nickel into the atmosphere, kickstarting the Great Dying.
The clock is ticking.
The nine metre-high waves that smashed into Minoan civilisation on Crete weren't caused by the volcano collapsing.
Mexico's Colima volcano erupted a few days ago, reminding the local population of the danger posed by the country's two active volcanos.
A volcanic eruption in 1815 triggered a year without a summer – prompting a flowering of nature writing that is all too relevant today.
Earth is the only planet in our solar system with both plate tectonics and life. Is there a connection?
When Mount Sinabung erupted in Indonesia, researchers were already in the area to investigate how locals coped with the ongoing risk.
What can we expect Australia's next volcanic eruption to be like? That depends where and when it happens, and it could be sooner than you think.
Scientists have found a way to narrow down the best signs that a specific volcano is about to blow.
Is this where it all began?
What happens beneath the surface before a volcano erupts? Can we predict when one will blow? And how can typhoons and melting glaciers contribute to big eruptions?
Thirty five years after the devastating eruption of Mount St Helens, a volcanologist looks back on how it unfolded – and how it forever changed our understanding of how volcanoes work.
Ash and mudflows are the biggest dangers from the unexpected eruption from the Calbuco volcano in Chile.
Two big eruptions have caused pyroclastic flows and high-altitude ash clouds over South America.
Earthquake analysis could help us understand the deep structure of volcanoes.
Natural disasters are becoming more frequent, with more people with less money exposed to a greater number of hazards.
