AB: In view of the devastating Sumitra-Andaman Islands earthquake and tsunami on December, 26th 2004, understating the Indian lithosphere beneath the Andaman Islands has gained great importance. This region is a transition zone between India & Burmese plates possessing high strain rate distribution. To estimate the co-seismic and post-seismic deformation, GPS data from IGS sites IISC, HYDE, LHAS, KUNM, PIMO, NTUS, DGAR, BAKO, COCO, MALE and a network of nine GPS sites in Andaman and Nicobar Islands have been analyzed using GAMIT/GLOBK software. Time series of the baselines and position coordinates indicate significant crustal deformation. The GPS results are discussed in conjunction with the litho-tectonics of the Andaman region.
