Lakeport, CA / Light shaking (MMI IV) / rattling, vibrating / 2-5 s : What a scare! This time my cats ran into the bedroom and three or four seconds later there was a shaking like a semi-truck was on the roof! i rolled onto the floor and covered the back of my head. I was praying and whimpering maybe crying just, just a little. my wife was fast to get to me and she reached down and grabbed me by filling both nose holes with her ring and pinky fingers jammed in and pulled me up to my knees and slapped me she slaps hard!! She told me "you know what that was for" and | 2 users found this interesting.
