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 ...

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

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...

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 ...

Earth's crust today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research finds. This early rocky shell featured chemical signatures previously ...

With steep walls and deep valleys, the Grand Canyon in the western United States or the massive gorges that saw through the margins of the Tibetan Plateau are some of the most awesome and spectacular ...

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

Scientists may have discovered the world's oldest arc-slicing fault in Northwestern Australia's remote deserts. The finding demonstrates that plate tectonic processes were operational at least 3 ...
