re: Chilling
The first shot seemed to be from a different location, and I like to think considerable time may have passed between that establishing shot and the next one of the wave. Still, a lot of people on the beach probably had no idea what hit them.
Alaska and Hawaii have tsunami warning systems. I wonder if our mainland coastal states are going to get on the ball, especially the West. There should be some middle ground between the low risk and the high cost of a too-elaborate system. Where I was staying in Hawaii, the ocean was thirty feet away and about three feet below the level of my porch. A tsunami with no warning would have been all she wrote.
