The aftershocks extend from northern Sumatra approximately 3 degrees North Latitude to the Andaman Islands approximately 14 degrees north. The significant shielding of Port Blair and Campbell Bay by steep mountainous outcrops may have contributed to the relatively low wave heights at these locations, whereas the open terrain along the eastern coast at Malacca and Hut Bay likely contributed to the great height of the tsunami waves   Indeed, many infrastructures near the coasts and buildings were harshly damaged by the waves.
A simple program of public education and awareness of the potential hazard could have saved many lives in the immediate area. There are many remote islands in the Nicobar, Andaman, Maldives and off the African coasts, so there are many unreported deaths.
Between February and Augustthe upper plate aftershock activity shifted from southeast of this fracture zone to northwest of it, suggesting that the lower plate left-lateral motion along the fracture zone may have induced a shift of the upper plate post-seismic activity along the Median Thrust Fault.
