But I'm a southern boy and the ground don't shake down here so it ould be best to get the opinion of a SoCal native to be on the safe side. lthough I have seen some drawings from guys out there and I'm not sure some of hem understand seismic very well either. Maybe Ken W will chime in here. He is the grand pooba of sway!
