Learn how seismic waves helped identify rare mantle earthquakes deep below Earth’s crust, offering new insight into the ...

Stanford University researchers have pulled back a curtain on a hidden part of Earth that rarely makes headlines. Their new work maps a strange kind of earthquake that starts deep below the crust, ...

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth's crust but in ...

Add Yahoo as a preferred source to see more of our stories on Google. Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust ...

Scientists at Stanford University have created the first global map of earthquakes occurring not in the Earth’s crust, but in ...

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust above it to "drip" and suck down rocks from across the continent. When you ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior ...

Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought.

Geologists have spent decades trying to punch through Earth’s crust to reach the mantle, the vast rocky layer that makes up ...
