An earthquake measuring 4.1 on the Richter Scale has been recorded in the middle of the Bristol Channel, making it the the fifth strongest UK earthquake since 2000.
According to the British Geological Survey Earthquake Seismology Team, the UK's national earthquake monitoring agency, the quake was five kilometres down and hit at 1.21pm today.
This is the North Devon earthquake seismograph via @BritGeoSurvey at Hartland.
The team report that the quake was felt at Dartmoor, Bristol, Taunton, Swansea, Llanelli, Exmouth, Barnstable, Gloucester and South Molton.
If you felt the earth shake, let us know.
The British Geological Survey operate a network of sensors across the UK to monitor both British and overseas earthquakes.
There are reports the quake was felt in Devon and South Wales, however here at thepacket.co.uk the earth did not move.
The earthquake was strong enough, in theory, to be noticed in the immediate area, with quakes of 4.0 to 4.9 causing "noticeable shaking of indoor objects and rattling noises. Felt by most people in the affected area. Slightly felt outside. Generally causes none to minimal damage. Moderate to significant damage very unlikely. Some objects may fall off shelves or be knocked over."
The Richter scale is a base-10 logarithmic scale. An earthquake that measures 5.0 on the Richter scale has a shaking amplitude ten times larger than one that measures 4.0.
