Evidence for distributed clockwise rotation of the crust in the northwestern United States from fault geometries and focal mechanisms Open
Paleomagnetic and GPS data indicate that Washington and Oregon have rotated clockwise for the past 16 Myr. Late Cenozoic and Quaternary fault geometries, seismicity lineaments, and focal mechanisms provide evidence that this rotation is ac…
