Earthquake This Morning
I was lying in bed this morning (after being up a while) and the bed started rocking. An earthquake! Wee!! It was really tiny, like 5 seconds total. It felt like someone was at the foot of the bed wiggling the frame a little.
Just now I just tried to wiggle the bed like the earthquake but the frame is too stiff. It was the building doing that wiggling! The motion was entirely horizontal, head-foot / east-west.
