At

there are some before and after satellite photos of some of the damaged

(or: http://www.digitalglobe.com then go to "Sample Images" and then to
"Tsunami Media Gallery")

As far as I have understood the changes in the coastline are not permanent,
except maybe for the Nicobars and a few other small islands.
