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 ...

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

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

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 ...

Scientists have traditionally focused on volcanic arcs as the main natural source of atmospheric carbon dioxide. These form ...

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 ...

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 ...

Africa gradually pulled apart along the East African rift, a slow tectonic shift that could have formed a new ocean and ...

This rift is slowly pulling the African continent apart, and over millions of years, it could isolate the eastern portion of ...

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

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 ...
