摘要: In this study, we investigate the March 24th 2011 Mw=6.8 Tarlay earthquake, Myanmar using Interferometric Synthetic Aperture Radar (InSAR) and inversion analysis. We firstly invert InSAR coseismic displacement from our previous study. The inversions are carried out in both single multi-patch model. slip of 2.5 meter single-patch solution is then combined with long-term rate geomorphological resulting an estimate 1,140-4,160 years recurrence period. Then, coulomb stress changes on nearby faults northern Thailand calculated. It found that western middle segments Mae Chan fault decreases significantly while increase eastern segment Chan, Ing Chiang Kham fault. Finally, results PSInSAR 29 Radarsat-2 images reveal postseismic rates between -24.4.6 to 34.5 millimeters per year
