Jonj, you must be new to the area. We've had many small quakes over the past 20 years and I can remember them back into the early 60's when I was in high school.
I worked a night shift in Plymouth during the 80's and in the computer room where I was we had lights suspended by wires. One night the building shook and the lights were swaying all over the place.
BTW, you don't want to be anywhere near a tornado. Back in the mid fifties, I lived bordering a field. Across the field, you could see the next street up.
I heard a noise looked towards the field and saw a small tornado, seems like it was 50-60 feet high, roaring across the field. It went over to the other street, and hit a one car garage. I watched at the garage was lifted about 15-20 ft in the air, rotated 360 degrees and then the wind stopped. The garage came straight down about 3 feet off it's foundation...in one piece but messed up for sure.
I guess it disturbed the wind enough to kill the twister.
I was a cupple hundred yards from this thing and I don't ever want to be any closer.
