The before (1st image in gif) and after (2nd image in gif) give a pretty clear sense of the scale of damage. From what I'm interpreting, it appears that the entire area contained in this image was inundated by the wave. The silver lining is in the 3rd image of the gif. After only four years (2009), the city looks much cleaner in aerial imagery, and reconstruction of the coastline seems to have taken place. Still, the appearance of the coastline is now dramatically different from its pre-tsunami shape.
The gif below shows June 2004, January 2005 (1 month after tsunami), and February 2009 (~4 years after tsunami):
