Alex,

Anything Nance writes is well worth reading. He is an airline pilot by profession and has taken on the airlines in print, as well.

I can't remember the name of the Napa town either, but it's not St. Helena. It's a very small town up in hot springs and mud bath country where the yuppies go for rejuvenation.

Now that you mention it, I too remember the guy with the special radio, but that's all I remember: a guy somewhere with a special radio. I remember the late Dr. Browning and his tinkerings and writings on earthquakes.

I think what gets to me the most is that for all we have learned about earthquakes--notably, since 1971's Sylmar quake--and what not to do, we still persist in flying in the face of nature, as evidenced by (among others) houses and other structures built on fill, or of unreinforced masonry, and--horrors--our newer and/or "reinforced" highways and bridges which obviously have not employed known earthquake technology to prevent or even mitigate failure.

Although the Cypress section of the 880 freeway was constructed in 1957, long before 1971, everything I have read since 1989 says that it was known in 1957 that the section which failed during Loma Prieta could not withstand even a moderate quake. It was built on fill, all the way down to a depth of at least 250 feet. (After Loma Prieta, the investigators drilled to that depth and never did hit bedrock.) Loma Preita shook the ground for less than 20 seconds. Makes you wonder what would happen if we were hit, as Alaska was, for several minutes.
