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 ...

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 ...

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

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

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 ...

Recent seismic research has unveiled a fascinating geological phenomenon occurring beneath the Pacific Northwest. The Earth’s crust is tearing apart, a process driven by tectonic forces in the region.

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 ...

At the boundaries between tectonic plates, narrow rifts can form as Earth's crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from belowground force ...

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