A massive 37-million-year-old underwater canyon reveals the fossil trace of an ancient Atlantic tectonic boundary.

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 ...

This groundbreaking research offers a comprehensive reconstruction of Earth’s tectonic evolution from 1.8 Ga to the present, bridging critical gaps in pre-Pangean plate dynamics. By merging three ...

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 ...

Geologists have reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. The team had predicted its existence over 10 years ago based on ...

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.

Learn about the movement of tectonic plates off the coast of northern California, a process that could incite major earthquakes. The hidden processes that drive earthquakes cause a lot of commotion ...
