It was scary. It started out as a good sized shake, then subsided a bit, then picked up steam again. The whole thing lasted well over 20 seconds which is an eternity for earthquakes. My wife, already holding our 4 month old, went straight to the nearest doorjam. I yanked my 3 year old out of her highchair, almost ripping the tray off in the process and joined my wife in the doorjam. The noise from all the rattling spooked the older one, for the rest of the evening she kept asking if "the noise was coming back", but she went to bed all smiles. Fortunately, we had no damage whatsoever. We had only one picture tip over on a desk. Nothing came off the walls. Nothing fell out of cabinets.
My wife was here for the Loma Prieta quake in '89 (the infamous World Series quake). That was over 7.0. She said she tried walking down the hall to where her folks were, but almost fell over and that putting her hands on the walls for support was pointless because the walls were swaying back and forth! I can't imagine what that would be like.
Regards,
Chris
