Deformation and stress field of Bam earthquake:
巴姆地震变形场和应力场：Ⅰ．用差分干涉雷达和Okada方法求解

The quantitative calculation of the displacement,deformation and stress fields of Bam Mw6.6 earthquake which occurred in the southeastern part of Iran at 1:56 UTC (5:26 in local time) on Decemher 26,2003 were carried out in this study.The coherence images and the surface displacement in LOS direction were derived using differential synthetic aperture radar intefferometry (D-InSAR) method.The location of the source fault was determined in the coherence images.The northern,eastern,and vertical displacement components simulated from Arg-e-Bain rupture were calculated using Okada's program.All three displacement components were projected to the LOS direction,and compared to the results from D-InSAR.The conclusion could be made that the Arg-e-Bam fault is the source rupture fault.The strain and stress fields induced by the earthquake were also calculated using Okada's program.
