Told this before on here :-

In 1979ish, I had just left the Pub and was lighting a Fag

when I felt the Subway rattling beneath my feet, not unusual.

I walked on, then stopped,  'Wait a minute, I'm not in Glasgow, I'm in Dumfries, they don't have an underground system'

Found out that night they'd been quite a big tremor (for UK) in Cumbria
