A new study from scientists at Scripps Institution of Oceanography at UC San Diego and the University of Chicago sheds light on a hotly contested debate in Earth sciences: when did plate subduction ...

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 ...

Large subduction-zone earthquakes leave scars on the continental slope in the deep sea.

The surface of our world has been in a constant state of flux for millions of years. Continents have wandered, oceans have ...

Tremors beneath Northern California show hidden plate movement, helping scientists better understand where future big earthquakes may occur.

Jessica DePaolis (second from left) and the team of researchers studied and compared sedimentary core samples in Montague Island, Alaska, and found evidence that four of the past eight earthquakes ...

Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods ...

Imagine a scenario where the Pacific Northwest gets pummeled by a magnitude nine earthquake, only to have California's most ...
