It was like a wave hitting soft rolling. Nothing sharp like the usual but moderate.

[FoxPro]

I think I was taking a shower about then.

Bummer...

[dfwgator]

Didn’t feel anything here in Texas.

[Churchillspirit]

[GeorgeWashingtonsGhost]

Probably just a bunker buster bomb test.. Oh wait, I forgot who the president is.

[Gator113]

I wish you well, but if this turns out bad, can I have your surviving guns and ammo?

[Melian]

Living in YL, I felt last night’s, this morning’s, and the smaller on just a few minutes ago. I’m riding the wave!

[Coldwater Creek]

I have family in Yorba Linda. They lost their home in the Whittier Narrows quake..........

[Lurking Libertarian]

Very noticeable here in Irvine, but I'm on the 12th floor of an office tower (skyscrapers in CA are built to sway in earthquakes). My wife was on the first floor of a building, also in Irvine, and didn't feel anything.

When I say very noticeable, you could really feel the building swaying, but there was no damage-- nothing fell off my shelves.
