A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating ...

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San ...

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

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

Tiny earthquakes have revealed potentially deadly hidden faults beneath California. By tracking swarms of very small tremors, ...

A hidden shard of ancient crust has been detected where California’s San Andreas system collides with the Cascadia subduction ...

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

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 ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

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 ...

A small amount of molten rock located under tectonic plates encourages them to move. This is what scientists have recently discovered. Their new model takes into account not only the velocity of ...

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 ...
