““In San Francisco, two people actually saw the earthquake. Jesse Cook, the police sergeant on duty in the produce market, saw it a moment after he became aware of panic among the horses all around him. Years later Cook recalled: “There was a deep rumble, deep and terrible, and then I could see it actually coming up Washington Street. The whole street was undulating. It was as if the waves of the ocean were coming towards me, billowing as they came.””
