Rotation and plate locking at the southern Cascadia subduction zone

Creator:: McCaffrey, Robert, Long, Maureen D., Goldfinger, Chris, Zwick, Peter C., Nabelek, John L., Johnson, Cheryl K., and Smith, Curt
Abstract:: Global Positioning System vectors and surface tilt rates are inverted simultaneously for the rotation of western Oregon and plate locking on the southern Cascadia subduction thrust fault. Plate locking appears to be largely offshore, consistent with earlier studies, and is sufficient to allow occasional great earthquakes inferred from geology. Clockwise...
