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 ...

Learn about the movement of tectonic plates off the coast of northern California, a process that could incite major ...

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

Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise ...

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 ...

The tectonic plates are among the most powerful forces on Earth, exerting tremendous influence over every single life that unfolds on this planet. They are both creators and destroyers, capable of ...

Venus, a scorching wasteland of a planet according to scientists, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. PROVIDENCE, R ...

Geoscientists have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas of Earth's crust long before it should be geologically altered by known plate-boundary ...

The two halves of the African continent are moving apart at a rate of a few millimeters each year, geologists have calculated ...

Invisible earthquakes are revealing a hidden tectonic puzzle beneath California’s most dangerous fault zone.
