4/20/2006: San Andreas Fault marked by fence movement
http://cellar.org/2006/SanAndreas.jpg
Excuse me for forgetting my notes on this one, I think it was an Earth sci pic of the day. In this case, this fence was straight when it was built, but since then shows the efforts of the Fault. And here is where the resident residents can give far better information than I can. All I remember is my Earth Science teacher, in 9th grade, explaining that California was not actually going to fall into the ocean, and that more likely eventually western LA was going to be next to eastern SF. I now realize that was hyperbole, but in the above shot you can actually see how the shifting affected this land; one side of it shifted one way while the other shifted t'other, or maybe didn't shift at all. |
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.

Here's the link. to the Earth Science story.
That was pretty funny, Brianna.:thumb: |

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