Now experts are warning “The Big One” could be even worse than feared due to a horrific domino effect that could wipe out the ...

Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in ...

That would have enabled more of this organic carbon—and carbonate accumulating in shallow water around Columbia—to be ...

It’s the 323rd anniversary of the last Cascadia Subduction Zone earthquake. We spend a fair amount of time thinking about the ‘Big One’ (and the ‘Really Big One’) in the Pacific Northwest. Today is ...

Subduction zones, where one tectonic plate dives underneath another, drive the world's most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

This study is led by Prof. Zhong-Hai Li (University of Chinese Academy of Sciences). The present solid Earth is actually active, with new plates generating in the mid-ocean ridges and some old plates ...

Subduction initiation marks the birth of a convergent plate boundary, where one tectonic plate begins to descend beneath another into the mantle. This process underpins the global plate-tectonic cycle ...

Around 510 million years ago, after a major gap in the geologic record, the world flooded. This gap, known as the Great Unconformity, starts at different ages in different places, but it always ...

Metamorphic rocks, like those pictured here, are commonly found in subduction zones. Researchers found that among other factors, the orientation of minerals within the rocks can affect seismic ...
