The complex mantle structure and tectonic history of the region have been previously studied, but the interactions of the subduction zones, transform plate boundary and stiff continental keel are ...

Transform boundaries neither create nor consume crust. Rather, two plates move against each other, building up tension, then releasing the tension in a sudden and often violent jerk. This sudden jerk ...

An icon in the shape of a lightning bolt. Impact Link Plate tectonics is the widely accepted theory that the Earth's crust is divided into several sections that float around on the mantle — the mostly ...

A hidden shard of ancient crust has been detected where California’s San Andreas system collides with the Cascadia subduction zone, reshaping how I understand the tectonic engine of the West Coast.
