Okay, i don't think the one i posted is the actual tsunami either. It looks very similar to picture number 2 on this slideshow (same pic?), which was taken 4 hours after it hit. The one posted before mine is the picture after (number 3) and according to that website is showing the water receding.

I wonder if any satellite pictures actually caught the wave itself as it was about to hit the shore. Call it morbid curiousity, but i really want to see what it looks like.
