Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

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

Yale-led research may have solved one of the biggest mysteries in geology — namely, why do tectonic plates beneath the Earth’s surface, which normally shift over the course of tens to hundreds of ...

Two studies show that the movement rate of plates carrying the Earth's crust may not be constant over time. This could provide a new explanation for the patterns observed in the speed of evolution and ...

A study published in the journal Tectonics has provided new insights into the forces that cause tectonic movements in Europe's most seismically active regions. Researchers used advanced satellite data ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. Carole ...

The cycling of water within Earth's interior regulates plate tectonics, volcanism, ocean volume, and climate stability, making it central to the planet's long-term evolution and habitability and a key ...

Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

Scientists are constantly on a mission to untangle how Earth alone among the planets was able to evolve complex life. We know that Earth's past internal movements of the tectonic plates under our feet ...

For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a University of California, Los Angeles (UCLA), scientist has discovered that the ...

A groundbreaking study has provided new insights into the forces that cause tectonic movements in Europe’s most seismically active regions. Researchers used advanced satellite data to track land ...

September 2017 saw a pair of weird earthquakes in Mexico. A magnitude 8.2 on September 8 just offshore the state of Chiapas was followed by a magnitude 7.1 on September 19—this time much closer to ...
