Shake, Rattle, and Roll--Again

So there DD#2 and I were at our Girl Scout meeting when the room began to shake. The feeling was subtle at first, beginning from the floor and moving up to the table. The shaking continued on for what seemed like a long time--relatively speaking. And then I asked the girls how strong they thought the quake was. I reminded them that every number increases the strength by a factor of ten. (These girls are in high school and they're all pretty good in math.)

The consensus was that the quake was between a 4 and a 4.5. I was quite surprised to discover that the preliminary indication is that the quake was a 5.4! I'm usually not that far off.

Hubs asked if I had the girls stand in the doorway. None of us felt that was necessary at the time. But the quake was a conversation stopper. Which is difficult to do with a group of 14- and 15-year old-girls.
