No injuries or damage have been reported following an earthquake in Cumbria measuring 3.5 on the Richter scale.
Many people were in bed when the tremor struck just before 11pm on Tuesday near Coniston and lasted for up to a minute. Some rushed out from their homes on to the street after the rude awakening.
The police and fire service received a number of calls from bewildered members of the public who were concerned at the late-night incident in which buildings wobbled.
Several listeners contacted radio stations in the county to say they compared the disruption to the sound of a washing machine. One said: "It was as if the washing machine was spinning with too much in it."
The earthquake was felt across the county and as far away as Lancashire, south-west Scotland, Northumberland and the Isle of Man.
Data from the British Geological Survey (BGS) showed the location of the quake at 1.2 miles north, north-west of Coniston, with a depth of 8.9 miles. The rumble was also flagged up by the US Geological Survey.
BGS head of seismology Dr Brian Baptie said: "We get an earthquake of this size somewhere in the UK roughly every 12-18 months. Damage is very unlikely.
"An earthquake of this size and depth might be felt up to 80-100km away. The earthquake has probably made windows and doors rattle and small objects might have been displaced."
A similar earthquake with a magnitude of 3.7 on the Richter scale shook south Cumbria on April 28, 2009.
There were no reports of casualties or damage following last year's mid-morning tremor which originated three miles south-east of Ulverston, and which was felt across Cumbria and Lancashire.
