Did you feel the Earth tremble?

(link taken off...just Google something about a 4.5 earthquake in Ottawa)

So that's what it was. I was wondering what the heck was going on for that 5 seconds. Everything just started shaking....I thought it was someone's car, but it was too strong and too long to be one. Oh well. Nothing in our apartment fell (not that I notice) and I don't think we have any structural damage, at least I hope not, with this crappy construction.
