Even long-lived subduction zones eventually die, and scientists think they are witnessing the death of one in the northern end of the Cascadia subduction zone.

Researchers have conducted detailed structural analyses of a fault zone in central Japan to identify the specific conditions that lead to devastating earthquake. The seismic slip processes that were ...

One of the main achievements in the Earth science is the development of plate tectonics theory in the 20 th century. It successfully explains the generation and extinction of oceanic plate from ...

Subduction zones occur where one tectonic plate dives under another. New computer modeling by Magali Billen, professor of earth and planetary sciences at UC Davis, shows why earthquakes on these ...

Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains ...

Around 510 million years ago, after a major gap in the geologic record, the world flooded. This gap, known as the Great Unconformity, starts at different ages in different places, but it always ...

For generations, scientists believed that the West Coast’s two great earthquake engines — the Cascadia subduction zone and the San Andreas fault — operated on separate geologic stages. One dives, one ...

Newly-released research led by the University of Washington (UW) showed that a feature scientists hypothesized was present along the Cascadia Subduction Zone is missing in places. What does that mean ...
