10:12pm Mountain time. I was sitting at my computer, typing a post for another thread when I suddenly felt a couple thumps. Nothing wierd... I just thought the neighbors were making noise. Then about 15 seconds later, the whole house started shifting side to side very roughly. I could hear the ground rumbling a little, and the house creaked a bit. The shelves and furniture were moving quite a bit, my DVDs even fell over. It was very intense. It lasted less then 10 seconds. I went outside and all my neighbors down the street were outside. We all confirmed what we experienced. Earthquakes are common around here (montana) but not often are they felt in largely populated areas, or this intense. It was cool!
