利用有限厚度弹性板模型反演了俄勒冈州西北部和华盛顿西南部的GPS矢量、地表倾斜和抬升速率，以估计沿着卡斯卡迪亚逆冲断层和覆盖板块基底的应力变化速率。这些数据是由沟槽80 km范围内的高剪切应力和库仑破坏函数（CFF）速率拟合的。相比之下，弹性半空间位错模型并不适合，并预测大量的锁定和海岸附近的CFF率升高。
GPS vectors and surface tilt and uplift rates from northwestern Oregon and southwestern Washington are inverted to estimate rates of stress changes along the Cascadia thrust fault and base of the overriding plate using a finite thickness elastic plate model. The data are fit by elevated shear stress and Coulomb Failure Function (CFF) rates within 80 km of the trench. By contrast, an elastic half‐space dislocation model does not fit as well and predicts significant amounts of locking and elevated CFF rates near the coast.
