6.8 Earthquake. 2001. Olympia, Washington.
The effects of an earthquake on a sand-tracing pendulum, discovered by Jason Ward.
Seismologists say that the “flower” at the center reflects the higher-frequency waves that arrived first; the outer, larger-amplitude oscillations record the lower-frequency waves that arrived later.
“You never think about an earthquake as being artistic — it’s violent and destructive,” Norman MacLeod, president of Gaelic Wolf Consulting in Port Townsend, told ABC News. “But in the middle of all that chaos, this fine, delicate artwork was created.”
