By observing the tree-ring-like growth records present in volcanic crystals, geologists are able to track volcanic activity and reconstruct the steps leading up to eruptions.
Studying the mineral olivine in kimberlite sheds some light on diamond origins.
The study also provides a new approach to solving one of the biggest enduring scientific mysteries: when did plate tectonics begin?
Several thousand earthquakes have been recorded near the Greek island since late January. So why is this happening?
Volcanoes and earthquakes are both natural phenomena driven by the dynamic processes that shape Earth’s interior and surface.
Rare earth elements aren’t necessarily rare – they’re just difficult to find in economically viable deposits.
We don’t generate power directly from volcanoes, but their presence is a sign that there are good geothermal resources underground that can be tapped.
Iceland is known as ‘the land of fire and ice’ for a reason.
Scientists were not previously certain how the precious stones arrived at the Earth’s surface.
One in ten people around the world live near an active volcano. Understanding the drivers of eruptions is crucial.
Some rocks will burn, and others will melt, depending on how they were formed and what minerals they contain.
As they shape the Earth, volcanoes inspire and terrify humans.
The eruption of Mauna Loa is a profound spiritual experience for many Native Hawaiians. An anthropologist explains Native American beliefs on the living Earth and volcanic lava.
A scientist who led one of the first projects to map the Hawaiian Islands’ deep volcanic plumbing explains what’s going on under the surface as Mauna Loa erupts.
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.
