A BGS spokesman said: "It looks like there was an earthquake originating in north Devon at 13:21 so we are just analysing it."
The size of the tremor is not yet known but reports on Twitter suggest that it was felt in north Devon and South Wales.

People in South Wales also reported feeling the ground shake.
