I was in the middle of a tutoring session this evening when I felt the floor rumbling. My first thought was that it was a truck driving by, but it continued and got stronger. When the table started moving a bit I finally realized, "It's an earthquake!" It stopped pretty quickly after that, but the experience definitely got my adrenaline pumping. I'm told that quakes in this area aren't as common as elsewhere in Japan, and usually aren't too strong either.
I'm organizing pictures and videos I took on my trip to the coast, and will post them soon.
