Overnight, an earthquake shook parts of Wales.
The 3.7 magnitude earthquake, with an epicentre just west of Crickhowell, Powys, occurred at 23:59 GMT on Friday, according to the British Geological Survey (BGS).
Nearly 30 miles away in Cardiff, BBC journalist Alex Humphreys claimed to have felt the "mini earthquake.".
She tweeted, "My entire bed trembled.". Others have called the experience "pretty scary.".
The BGS estimated the depth of the earthquake at 1.2 kilometers (1 miles).
The 1984 Llyn Peninsula earthquake in Gwynedd, which measured 5.4, was the largest earthquake ever recorded in the UK. 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.
Smaller earthquakes are common in Wales, according to the BGS, with 70 of them measuring more than 3 points five between 1727 and 1984.
