Paleo-reconstruction of the plate boundary system across Cascadia, including the region south of the MTJ using finite rotation poles from DeMets and Merkouriev (2016) and Wilson (1993)—the methodology is described in the supporting material. The paleo-shorelines shown in the ~ 6–5 Ma reconstructions are interpolated from Lock et al. (2006). a ~ 6–5 Ma reconstruction showing the approximate location of the MCC and SNGV deformational footprints and a schematic paleo-(NNW component)-GPS field based on reconstructed plate motions. b Present-day map of the Cascadia plate boundary system showing the approximate location of the MCC and SNGV deformational footprints (based on results from this study) and a schematic of the observed NNW component of the GPS field. c ~ 6–5 Ma reconstruction showing the approximate location of the subduction-related deformational footprint and a schematic paleo-(subduction component)-GPS field based on reconstructed plate motions. d Present-day map of the Cascadia plate boundary system showing the approximate location of the subduction coupling deformational footprints and a schematic of the observed subduction component of the GPS field. e ~ 6–5 Ma reconstruction showing the approximate location of the subduction, MCC and SNGV deformational footprints and a schematic total paleo-GPS field based on reconstructed plate motions. f Present-day map of the Cascadia plate boundary system showing the approximate location of the subduction, MCC and SNGV deformational footprints and a schematic of the observed total GPS field
