    • The variability of rate estimation from paleoseismologic study depends on the method used to measure the net slip vector (2-4). At the latitude of the GPS profile (at ∼39.3°N), we refer to the CNSB as the area including the Rainbow Mountain, Fourmile Flat, Fairview Peak, and Sand Springs faults (4). This corresponds to the area between -118.645° and -117.712° between the GPS sites B220 and C200 of (7).

    • For SAR processing we used the commercial FOCUS processor, and for InSAR processing we used ROI_PAC V2.2.1 software (Jet Propulsion Laboratory). We did not reestimate the baseline between the satellite orbits with the use of topographic information because this may introduce second-order phase ramps. For InSAR studies over the Basin and Range, see (36).

    • w 6.8 to 7 (3, 21), predominantly a strike-slip earthquake. Modeling this earthquake showed that the postseismic deformation in LOS direction is more than an order of magnitude smaller than for the Dixie Valley earthquake, and thus it can be safely neglected.

    • note
    • The postseismic model predicts at the latitude of the GPS profile (∼39.3°N) a 2-mm extension across the CNSB in a roughly east-west direction. Removing this from the GPS vectors of (7) leaves secular deformation of 0 to 2 mm/year, also roughly oriented east-west. Further north at the latitude of another GPS profile at 41°N latitude (37), the predicted postseismic deformation is less than 1 mm/year.
