Earth has liquid rock inside. Here’s what happens to that rock to make lava happen.
Drones can be used to collect gas samples from active volcanoes, where it is too dangerous for researchers. This data can be then used to predict the frequency and severity of eruptions.
There’s a curious 200-million-year rhythm to Earth’s crust production. Now, it seems like our very place in the galaxy is tied to it.
The eruption is akin to a weapons-grade chemical explosion, and there could be several weeks or even years of major volcanic unrest to follow.
A previously unknown filtering process inside some volcanoes can cause magma to shoot out like champagne from a bottle - and perhaps even make it easier to forecast when a volcano is about to erupt.
I look at fragments of the Earth’s mantle under a microscope to learn how fast molten rock moves from deep in the Earth to the surface. This can help us prepare for future volcanic eruptions.
The eruption prompted the evacuation of about 20,000 people, with no casualties.
The rocks provide rare evidence of a time when Earth’s surface was a deep sea of incandescent magma.
Exploration of ancient magma chambers in fossil volcanoes has the potential to provide new sources of metals that will facilitate environmentally friendly technologies.
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.
