A small earthquake shook houses overnight in Cornwall, it has emerged.
The 2.2-magnitude quake hit Bodmin at 2.40am on Sunday and lasted just a few seconds, the British Geological Society said.
There were no reports of damage but the tremor could be felt in Bodmin, Liskeard, St Austell, Padstow, Camborne, Wadebridge and Callington.
Sue Dibble, from St Tudy, told the BBC: "It was very loud, like a whooshing and the house and bed were shaking. I thought I'd imagined it."
A number of earthquakes are felt by people every year in the UK, but most of these are very small and cause no damage, the society said.
The largest known earthquake in the UK occurred in the North Sea on June 7 1931, 60 miles offshore near the Dogger Bank with a magnitude of 6.1.
