Crescent City is a 'tsunami magnet'
Thirty-six hours? I had no idea. I thought harbors were supposed to be havens.



The word tsunami is Japanese for harbor wave, and many times the worst physical damage comes once the waves enter the confines of a harbor, said Costas Synolakis, professor of civil and environmental engineering and director of the Tsunami Research Center at the University of Southern California.

"It looks like what happens if you hit a drum," Synolakis said. "You create waves with just one hit to it, but the drum keeps vibrating. What that means is it takes a couple waves to come in. Then you set up these back and forth waves inside the harbor that end up reinforcing each other. Crescent City took about 36 hours for the oscillation to die down."

1. Crescent City is in an area that is like the "Big Nose" of the west coast of the Northern Hemisphere
Anything that is going to hit that area goes for the nose first. (Just my observation, of course)

2. I surf down there quite a bit and
the biggest problem I see in the harbor is the mouth is too small, even a draining ebb to low tide will produce 6 knot currents through the mouth.
Not smart.
