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 rotation of most of Oregon about a nearby pole is
likely driven by collapse of the Basin and Range and results
in shortening in NW Washington State. The rotation pole
lies along the Olympic - Wallowa lineament and explains the
predominance of extension south of the pole and contraction
north of it.
