I can't believe it! I felt it (maybe not as badly as I could have done, as I'm in a terrace house) but I had no idea what it was til this morning! I was half asleep when it happened, and I heard at least one of my housemates get up. It was quite violent shaking, but it stopped after 10secs and so I stopped being worried about it... Nothing fell off my shelves so it can't have been too bad... Anyone NOT feel it?
