Unexpected shaking

You don’t see this everyday – an earthquake in the UK, large enough to cause damage. The thumbnail will take you to the USGS Earthquake Hazard website, a great source of near-real-time data for your mashups. I was at the epicentre of a magnitude 5 earthquake in the UK on Boxing Day in 1979. It was strong enough to shake the baubles from the Christmas tree and move furniture but to my lasting regret, I slept through the entire event.
