The largest earthquake to hit the UK for a decade has struck in Wales and been felt as far away as Birmingham, the British Geological Survey (BGS) has confirmed.
The tremor's epicentre was around 20km north, north east of Swansea and it had a magnitude of 4.4.
The quake's hypocentre, the point where the shift actually happened, was said to have been around 8km under the surface of the earth.
The BGS said earthquakes of this magnitude happen around once every two to three years.
A spokesman for the BGS said: "It was a reasonably sized earthquake. This earthquake has been felt across a large area of Wales and England with the furthest reports so far from Birmingham and Devon.
