EARTHQUAKE!!

I've been in two small earthquakes before, but that isn't what my mind went to when the house started shaking.  My first thought was that the washing machine was lopsided and going on a hard core spin cycle.  My second thought was that I didn't have a load of laundry on.  I couldn't figure out what it was - got up to see if there was a big truck in the driveway, wondered if it was the fridge breaking...  it lasted at least 30 seconds.  I think because we don't live in a traditional earthquake zone I didn't twig to it until later.  No real damage, but I think it wiggled the satellite dish out of position - World Cup is not as crisp as before.  5.5 on the richter scale, epicentre at least 250km away.
