I was just settling down after posting my gibberish in the thread thread when I started to wobble, with the headboard banging against the wall and a kind of rippling noise went through the wall. As I was so relaxed, I knew instantly that it was an earthquake.
After a short while I forced myself up to have a look at the USGS site who confirmed what I already knew. I then spent the next hour or so watching the BBC News and Sky News as I couldn't sleep expecting an aftershock.
I'm feeling quite tired now.
