About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

In 2021, geologists animated a video that shows how Earth's tectonic plates moved over the last billion years. The plates move together and apart at the speed of fingernail growth, and the video ...

Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents in motion and drives life on Earth. But what ...

The Mendocino Triple Junction is the meeting point of three tectonic plates. Using data from tiny earthquakes, researchers at USGS, UC Davis and CU Boulder propose a new model for this seismic zone.

Schematic tectonic evolution model for the Wutai Complex during Late Archean (a) Subduction setting (~2543 Ma); shows subduction-related metasomatic agents which influenced the lithological and ...

Along coastal California, the possibility of earthquakes and landslides are commonly prefaced by the phrase, 'not if, but when.' This precarious reality is now a bit more predictable thanks to ...

When tectonic plates sink into the Earth they look like slinky snakes! That's according to a study published in Nature, which helps answer a long standing question about what happens to tectonic ...
