What appears to be three tectonic plates in a map may act like five pieces that move underground. Northern California ...

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 ...

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

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 ...

Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Many seismologists and researchers have long believed the Earth ...

Researchers have detected a previously unknown layer of partially molten rock beneath Earth's crust. The discovery could help scientists learn more about the movements of Earth's tectonic plates, ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy.

Earth’s Ediacaran Period, roughly 630 to 540 million years ago, has always been something of a magnetic minefield for scientists. During earlier and later time periods, tectonic plates kept a steady ...

The Earth with the upper mantle revealed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock in a key region just below the tectonic ...
