Well it's not every day you get woken up by an earthquake! At 5.32am this morning a bang and shaking woke John and I up (can now officially say that Craig will sleep through an earthquake!). Checking the house showed nothing had exploded, neighbours' lights confirmed other people had woken up too - and the terminal lights seemed to indicate no explosion in that direction.
It has been confirmed as an earthquake of 3.3 magnitude. Fits in with my OU course - spooky!
