Many California towns will be inundated when that big quake finally happens

I grew up in Humboldt Co, CA. My family was from Petrolia, a tiny little town right on top of the triple junction of the plates.

Local Indian tribes tell the story of when a tidal wave wiped out the area around Humboldt Bay. Long considered myth it was confirmed some years ago by a group of students from HSU.

They were digging in the Arcata Bottoms, a fertile flat plain north of the bay, and discovered tree stumps buried some 12-16 feet below the surface. Eventually it was reasoned that the bay had dropped, in one moment, that far below sea level. Since then, similar locations have been found up the coast all the way to Washington.

If you look at the maps, there are several towns, Arcata, Eureka, Ferndale, and Fortuna, that will all be inundated when that big quake finally happens. Depending on the height of the waves, places like McKinleyville, Blue Lake, and down the valley to the south following 101 will also be in danger. I have a lot of family and friends still in the area, I’m not looking forward to that day. I’ve always thought the damage estimates were entirely too low.

If you look at the USGS fault line maps, they end the San Andreas just a few miles south of the southern tip of the Cascadia. The northern end of the SA used to be around Santa Rosa, Ca. Over the years they keep moving the tip north. IMO they will eventually just acknowledge the obvious and connect the line. It is one gigantic fault line. I think it is possible that a large quake on either end could trigger the other. (As for culling the liberal herd-there are plenty of really good conservatives out there).
