Wales has experienced overnight shaking due to an earthquake.
The 3.7 magnitude earthquake, which occurred at 23:59 GMT on Friday, had its epicenter just west of Crickhowell, Powys, according to the British Geological Survey (BGS).
The "mini earthquake" was felt in Cardiff, which is about 30 miles away, according to BBC journalist Alex Humphreys.
She tweeted, "My whole bed shook.". Some people have called it a "pretty scary" experience.
The BGS estimated the depth of the earthquake to be two kilometers (km), or one and a half miles.
The largest earthquake to ever be felt in the UK, which measured 5.4, occurred on the Llyn Peninsula in Gwynedd in 1984. It started at a depth of more than 12 miles (20 km), and the shock wave it produced could have easily caused significant structural damage.
With 70 quakes measuring more than 3.5 between 1727 and 1984, the BGS claimed that smaller quakes are common in Wales.
