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

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 history of Earth is written on the great tablets of tectonic plates. The motions of plates shaped land masses, formed ...

A new study from Harvard geoscientists reports the oldest direct evidence yet of plate motion, dating to 3.5 billion years ago. In a study published March 19 in Science, the researchers found that ...

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 ...

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.

A figure from the study showing rock dripping from the craton. The researchers hypothesize that the dripping is caused by the remnants of the subducting Farallon slab below the craton. Researchers ...

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 ...

Scientists have reconstructed a long-lost tectonic plate that may have given rise to an arc of volcanoes in the Pacific Ocean 60 million years ago. The plate, dubbed Resurrection, has long been ...
