      4.3 according to CNN. There were some books at the office that hit the floor, but I didn’t see anything amiss at home this morning.

    2. whig Says:

      I just posted the current USGS data, looks like it got estimated downward a bit to 4.2.

    3. Grace Says:

      WOW…I’m fascinated by the numbers showing up on this post! First, it was posted at 4:44. And apparently, the earthquake was almost at 4:44 as well.

      Lots of shaking going on. We had an earthquake down here last Sunday morning at 3:30. Then that huge quake hit Japan on Monday (if I remember right).

      Mother Earth is rockin’

      I think it’s a good way to echolocate myself. Although I post semi-pseudonymously many people know my name and where I am, but a lot of other people wouldn’t have any idea and I don’t want to be more specific than necessary to encourage stalkers or anything. But we do need to maintain a certain amount of visibility when addressing this administration, thus making ourselves harder to disappear.
