4.1 Comparison of Stress-driven Afterslip for Different Published Coseismic Rupture Models
We first compute afterslip-only models for each of the published coseismic slip models. We allow both up-dip and down-dip afterslip and also along-strike afterslip, but our observations are most sensitive to the downdip portion of the afterslip due to the distribution of GPS sites (Figure 1). Comparing the afterslip predictions (Figure 5), we find that the Liu et al. (2022), and Elliott et al. (2022), models both produce large azimuthal misfits at two peninsula sites AC21 and AB13, while the Ye et al. (2022) model, which has a more compact coseismic slip area, does not show this systematic misfit.
