Geophysicists use sound waves to build a picture of the magma and rock beneath this active volcano, most of which is underwater. It's like CT scanning the Earth.

Scientists say they've found a new method to help predict when volcanoes will erupt, based on data crunched from an eruption last year in Hawaii.
Compared to Earth, more "oomph" is required to bring magma to the surface of Mars, and this is probably why we haven't seen any recent eruptions on the red planet.
Important points about volcanoes: location matters, explosiveness can be predicted to an extent, and fast-moving flows of volcanic materials (known as pyroclastic flows) are deadly.
The remote Pilbara region of Western Australian formed many billions of years ago when the Earth was much hotter and the crust softer than it is today.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
Satellite research in Ethiopia is opening up a new frontier in the hunt for geothermal power.
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?
