Gina M. Schmalzle coauthored a study of persistent creep in the Cascadia subduction zone. It combines station-position time series, uplift measurements and paleoseismic subsidence to estimate plate locking and compare deformation over different timescales.[ref]
Central Cascadia subduction zone creep by Gina M. Schmalzle and others. Abstract: GPS, tide-gauge/levelling and paleoseismic constraints
Reduced interseismic uplift and reduced earthquake subsidence motivate partial-creep models for central Cascadia. The proposed connection with Siletzia involves permeability and pore pressure; the measured deformation and the mechanism proposed to explain it remain distinct parts of the argument.
