Test results for inversion uncertainties and the effect of the source region on the PHS slab. a The best-fitting solution for the SLAB case, which is the same as the mean solution for 5000 slip inversions using the observed data with Gaussian noise according to uncertainties. b Standard deviation of slip on each subfault based on the square root of the diagonal of the covariance matrix. c Standard deviation of slip estimated from Monte Carlo simulations. d Difference of the inverted slip on PAC slab with and without PHS source region. Positive and negative color scales for panels (a, d) denote magnitude of slip with positive and negative dip components, respectively
