Earthquake hits south west Britain
An earthquake has been recorded under the Bristol Channel, the British Geological Survey (BGS) has confirmed.
The 4.1 magnitude quake happened at about 13:21 GMT and was felt in Devon, south Wales and Somerset.
Some residents reported their houses rocking, and likened the tremors to a "heavy truck going up the road".
The BBC's Hywel Griffith and Science Editor David Shukman report.
