A village in Cornwall has been rocked by an earthquake which 'felt like a hand grenade' had gone off.
Data just released by the British Geological Survey reveals that the earth tremor occurred on Friday, June 3, at 7.13pm.
The microseism happened at Constantine, near Falmouth, over the Queen's Jubilee long weekend.
The BGS' experts say it was a shallow earthquake, only 5km deep.
Tremors from a shallow earthquake are usually more intense than deep earthquakes.
However, this particular seism only had a magnitude of 0.1 - equivalent to a hand grenade.
Earthquakes with a magnitude below 2.5 are not usually felt but can be recorded by seismographs.
There are hundreds of thousands of similar small earthquakes every year around the world, including in Cornwall.
In February a 3.2 magnitude earthquake rocked the West Midlands, with residents reporting 'shaking' and explosion-like sounds in the Birmingham area.
Residents described being left "terrified" after the quake hit 7km north west of Birmingham, with a depth of 10km.
Homeowners living in Walsall described how they were left fearing the worst as many were jolted from their beds in the middle of the night.
It is unusual for the UK to suffer earthquakes as it does not sit on a fault line between tectonic plates and when they do hit they are not so severe.
The strongest recorded British earthquake took place near the Dogger Bank, in 1931, which had a powerful magnitude of 6.1.
It struck 60 miles offshore but still caused damage to buildings on the east coast of England.
