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.
