10/31: Earthquake rose

Cyc sends along this pic of how an earthquake has affected shifting sands... no other details available, but it's interesting, innit?

So...

Is that what the L.A. Basin is going to look like after "The Big One"?

I want to add this:

I found this image at www.earthquakerose.com .

Basically, what happened was that during the Seattle Earthquake this year, the shifting motions of the ground caused the pendulum to move back and forth in a seemingly random motion. That motion carved an image of a "rose" onto the sand base.

Even in nature's fury, there's beauty being created. =)

Now *that* is very, very cool.

Reminds me of the Lissajous figure demonstrations at the Franklin Institute; the big old compound pendulum sand tables and the plate you could cover with sand and tne vibra with a rosined bow.

Boy, that place has really hit the skids in the process of becoming finacially viable and damage resistant to hordes of unsupervised brats. It's a microcosm of everything tha's bad about the educational establishment.

It used to be a temple to the sciences, now it's just about one stop above Sesame Place.

Is it just my imagination or does that thing look somewhat symmetrical?

And if so, if you drew a line through the major axis, would that line be normal to the propogation direction of the earthquake waves?

If you had two of these dishes spaced miles apart, you could find where these lines intersected, and that would be the epicenter?

Reminds me of looking down into a lovely glass of Guiness. The beauty of nature.

Yea, it does, doesn't it. Either that or "dhamsaic's syndrome"....see the "Pet Peeves" thread.
