I was really freaked out by the earthquake as well. I didn't even feel it but I was driving at the time and the radio started yelling "5.9 in Mineral, Virginia!"
Apparently, because the East Coast has more dense rock in it than the West coast, the quake was felt over a much wider distance.
I bet they'll be selling "quake preparation kits" tomorrow at all the grocery stores.
Sorry to get so off topic... lol, when I heard of the earthquake, I didn't even think of my tanks. I immediately thought "OH, I hope I feel some shaking!" Good job me, want to be hit by an earthquake.
