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.
The planet is more similar to Earth than any other – except when it comes to supporting life.
In Iceland, an audacious project to tap into magma deep below the surface may usher in a new era of geothermal power.
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.
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?
