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

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

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 ...

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

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

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 ...

An enduring question in geology is when Earth’s tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ...

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 ...

In deep Earth, rocks take up and release water all the time, and the effects can be wide reaching. Dehydration can cause rocks to crack and trigger earthquakes, and over geologic timescales, this ...

Ancient rocks on the coast of Oman that were once driven deep down toward Earth's mantle may reveal new insights into subduction, an important tectonic process that fuels volcanoes and creates ...

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 ...

A new study introduces a novel way for tectonic plates — massive sheets of rock that jostle for position in the Earth’s crust and upper mantle — to bend and sink. It’s a bit of planetary Pilates that ...
