That video is amazing!

That said, my geology teacher is going to have a field day with this when we meet up for class today. She starts every class by pulling up a chart of seismic activity, and our last class was before the VA earthquake!

I always thought it had something to do with animals being able to hear earthquakes before we can feel them. There are three different kinds of energy waves associated with earthquakes, and the first/fastest one (p wave) travels similarly to sonic waves, so I just assumed that there was some kind of noise associated that's outside our hearing range. I think the second and third type are what cause most of the actual shaking.

None of us geologists at my work felt anything, nor did we get worked up about it. working at a nuclear plant is exciiting enough.

Agreed... As a native West Coaster living in DC, my first instinct WAS to drop and cover and it kind of felt wrong running out of the building with everyone else. I wouldn't have done that in California, but here I just feel like it's a different ballgame because these buildings aren't built to withstand essentially anything.
