investigation of mechanisms involved in the postseismic displacement following 2003 bam earthquake in iran using radar images

in this paper, bam postseismic deformations during 7 years after earthquake have been extracted using persistent scatterer interferometry technique. the time series are inverted for the afterslip distribution on an extension of the coseismic rupture. the estimated postseismic slip value is 20.45±0.38 cm. most of the postseismic displacement field can be explained in terms of fault slip. the results of postseismic motion modeling indicate that the poroelastic rebound can be detected using the line-of-sight data and the effect of viscoelastic relaxation in postseismic displacement is negligible.
