A Magnitude 4.1 Earthquake Recorded in the Bristol Channel

A Magnitude 4.1 Earthquake Recorded in the Bristol Channel

The British Geological Survey (BGS) has confirmed the recording of a magnitude 4.1 earthquake in the Bristol Channel at 13:21 on Tuesday 20th February.

Ground shaking from the earthquake was widely felt in north Devon and south Wales. Little damage is expected from an event of this magnitude and now injuries have yet been reported.

It is not unknown for parts of the British Isles to experience small to moderate size earthquakes. These are due to the sudden release of built-up stress on old fractures and faults in the ground.

The image above shows the seismograph recording of the the earthquake on the Hartland (HTL) seismic station.
