Three sets of earth shudders, about 10 minutes ago... each lasting about 3-5 seconds.

Confusing

The message preceeding yours in my Friends list is a post by kwalton showing her freshly baked Challah. It looked like you were commenting on it, asking what the Challah was. ;-)

Earthquakes!!

Sorry to lazy to post this as an actual link:

You really should keep an eye on this. You guys have been having lots of earthquakes lately across the bay. Of course mt lassen up here has had quite a few as well... thank good ness I am out of range of it though.

That link hasn't got any from right when he felt them, though. Might have been something else. The ones around Lassen have been tiny. Every so rarely often, Redding gets a quake worth noticing. I was there for one, but it was centered near Oroville.

Feeling earthquakes from where they happen is quite different for people. I had been on the epicenter of one and didn't really feel it, then other times I am miles away from an earthquake and it shook me right off the sofa.

It also depends a lot on soil type, depth of the hypocenter, and the geology between the epicenter and where it's felt. That's why there could be so much damage in the Santa Cruz mountains, Los Gatos, Palo Alto, San Francisco, and Oakland, but less in Hayward and Fremont. Geological structures underground actually bent and deflected waves in some places, amplified them in another.

John McPhee's "Assembling California" does a good job of explaining it. I get hot and bothered about such things.

You too?? Glad to see I am not the only one getting worked up over dirt!

You explained it better than I... course not surprising since your extensive vocabulary over shadows mine by like 100 fold.
