Abstract

In this paper, Bam post-seismic deformations during 7 years after earthquake have been extracted using PERSISTENT SCATTERER INTERFEROMETRY technique. Deformation time series have been extracted using the method of constant scattering interferometry techniques. The results illustrate that the maximum amount of uplift and subsidence displacements in Line Of Sight direction during 2004 to 2010 after the earthquake are and centimeters, respectively. The time series are inverted for the AFTERSLIP distribution on an extension of the coseismic rupture. The estimated post-seismic slip value is 20.45±0.38 cm. Most of the post-seismic displacement field can be explained in terms of fault slip which is the most likely mechanism involved in the post-seismic deformation in the Bam earthquake. The results of post-seismic motion modeling indicate that the POROELASTIC REBOUND can be detected using the Line-Of-Sight data and the effect of VISCOELASTIC RELAXATION in post-seismic displacement is negligible.
