The idea that earthquakes release stress by a single strong quake along a single fault plane may need to be corrected. A recent study by researchers from the Karlsruhe Institute of Technology (KIT) with the participation ...

As an important subduction component, altered oceanic crust (AOC) is widely distributed on the oceanic subducting slab and may contribute significantly to the chemistry of arc magmas. However, identifying this contribution ...

The present solid Earth is actually active, with new plates generating in the mid-ocean ridges and some old plates sinking back into the interior through subduction zones. Subduction is thus a key process of the tectonics ...

Our world may seem fragile, but Earth has been around for a very long time. If we ventured far back into the past, would we reach a time when it looked fundamentally different?

At subduction zones, slabs of lithosphere sink into Earth's mantle. Understanding how these slabs fit into mantle convection cells is important because of the role these movements play in plate tectonics. It's also difficult, ...

Temperature and shear stress are two influential variables that affect faulting and seismicity in subduction zones, where tectonic plates converge. Yet because earthquakes originate tens of kilometers below Earth's surface ...

Einstein's inexhaustible field equations just keep on predicting weird stellar objects, and the latest one is a doozy—so strap on your helmet, inside of which is another helmet, encasing still yet another helmet. This headgear ...
A new study, resorting to computational models, predicts that a subduction zone currently below the Gibraltar Strait will propagate further inside the Atlantic and contribute to forming an Atlantic subduction system—an ...

Studying a rock is like reading a book. The rock has a story to tell, says Frieder Klein, an associate scientist in the Marine Chemistry & Geochemistry Department at the Woods Hole Oceanographic Institution (WHOI).

The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there.
