"The turbulent white water is directly in front of the so called hills."
Not really. It only looks like it because of the telephoto lens used by the photographer. It is actually miles away.
If you look carefully, you can see a radio tower on that "huge wall of water". Honestly......you are mistaken. A wave that size wouldn't have left any survivors in that part of Thailand.
The rock formation on the right side of the first picture on this thread is the same rock formation that can be seen like a big finger in the center/left of this picture. The beach these people were enjoying was to the left of the finger, and to the right of the other rock formation.
The mountains in the first picture above can be clearly seen in the upper right corner of this picture. You can also clearly see the angle that the wave was coming in without being blocked by the hills.
"The blue shape behind the breaking white water is not a hill it is the tsunami wave."
Those are hills, and the waves were not "several stories tall."
