Temporal evolution for the viscosity (upper row) and compositional (lower row) field of the 3D reference case showing LLSVP-sourced plume-induced subduction initiation. (a–) Model snapshots at 0 Myr ...

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 Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the deep-seated ...

Kinematic plate reconstructions and high-resolution global dynamic models developed to quantify the amount of Pacific Plate motion change associated with the Hawaiian -- Emperor Bend. Scientists are ...

A new study makes the case that the solar system’s hellish second planet once may have had plate tectonics that could have made it more hospitable to life. By Kenneth Chang Venus today is not like ...

The desert floor in Ethiopia looks fixed and ancient, but it is moving. Across the Afar region and down the East African Rift ...
