4/20/2006: San Andreas Fault marked by fence movement
Trilby Thursday Apr 20 03:24 PM
Yeah, that would be my excuse. Some foreman would come along and tell me the fence I just built was crooked and I'd say it was San Andreas's fault.

Shouldn't the road be affected too?

Maybe the road has been re-paved since the fence was built. The fence looks real old.

The San Andreas Fault is an example of a right-lateral fault. That is, the slippage appears to move to the right looking across the fault line.

The April National Geographic has a piece about the San Francisco quake. In it, they have a picture of a fence that was originally constructed something like 75 years ago. Although it was rebuilt in the 1970's, according to the caption, it was rebuilt exactly as it was when it was torn down. Therefore, you see a displacement between sections of the fence of something like 15 feet...

...and here is the same fence, albeit not the same exact NG picture.

When I was at school there was a geography textbook with a great aerial shot of a long straight highway running through a desert. In the middle of the highway it did a sudden right-left turn where an eartquake had caused the land to slip sideways by about 20 metres. I've googled for this pic but unfortunately I can't find it.

I'm sorry, I couldn't resist.

that seems to be my response to most of your posts

Very different setup on the electric fence than what I'm used to seeing.

I can't figure this one out.
Prepare to be befuddled.

I like how someone posted a sign in the background of the picture so that Mother Nature would know what to do.

That reminds me of a place in Iowa where the mainstreet through town takes a right-lefter. This was due to a datum update or change and it turns ou the road perfectly follows a line of latitude. So as they were building it, they had to update it as well...

Maybe it's a tourist attraction.

There is a fault line that crosses I-80 just west of Fairfield, California on the way to Vallejo. Every few years or so, they have to repave a couple yards of asphalt across the freeway, and repair the dividing wall as it breaks apart. My dad has commuted this stretch of 80 for over 20 years and I commuted it for 3, so we both have been able to see it. Sorry, no pictures tho. Maybe someone else has seen it?
