This is the most complete… and amazing view of the tsunami I’ve seen. And right at the very end is the first, and only shot I’ve seen of the water receding. I think the reason that we haven’t seen the normal tsunami sequence.. ebb, flood, ebb, flood, etc. is that the seawall along the Japanese coast… something like 3-5 meters high… eliminated it. I.e., once the water got over the seawall (since it was 7-10 meters high), it stayed there… the seawall blocking it from receding back out to sea. What an irony!
