In this video, the issue of bays and inlets concentrating water during a tsunami and causing the water level to rise is illustrated very clearly- as a
village behind a sea wall is wiped out. For most events the giant sea wall would have probably protected them, but the sheer volume of water generated
from the March 11 Japan 9+ quake was just too much for even this well protected village.
The video picks up after the quake, and after the water in the inlet had already appeared to be drawn out, as so often happens right before the waves
hit. This leaves some boats beached at the docks, if you look carefully. And then...Here comes the water...
a little village by the small bay named ryoishi was hit by tsunami. it started looking big ebb but people knows whats coming next.
Moving water is an incredibly destructive force, as evident with this recent earthquake and resulting tsunami. Further evidence for the level of power
and influence water can be found in the carving of lakes, streams, coastlines, and its ability to influence manmade structures. Interesting to try and
comprehend that a relatively minor increase in sea level has the potential to negatively affect millions of people. Water will continue to shape the
face of our planet through relatively benign processes or destructive ones.

There was a Tsunami in a bay similar to the one in the video in Alaska....sometime in the 50's I think. The narrowness of the inlet caused the Tsunami
wave to reach incredible heights. I forget the exact maximum of the wave but it was astounding. Maybe someone here has better details about that one.
One problem with that sea wall, is that once the water goes over it, the wall is probably going to do more harm than good, because any water that does
go over it is going to have a hard time getting back to the ocean on the subsequent withdraw. The wall will trap most of it, and keep it in the
village area, instead of it going back to sea. I dunno, what's worse, getting sucked out to sea or drowning behind the wall?
