Epicentre of quake, which hit just before midnight on Friday, was north of Brynmawr and west of Crickhowell
An earthquake has shaken parts of south Wales.

The British Geological Survey (BGS) said the 3.7 magnitude quake happened at 23:59 GMT on Friday. The epicentre was just north of Brynmawr, Blaenau Gwent and west of Crickhowell, Powys.

It was felt by residents across the region, including Abergavenny, Crickhowell, Llangynidr, Llanover and Llanfoist, with many saying that furniture and windows shook.

Gwent police said it had received "multiple calls" overnight but it was "business as usual" for the force.

"My whole bed shook," one person tweeted. Others described it as a "scary" experience and some said it "felt as though their property had been hit by a car".

Others described objects such as bookshelves and desks moving, and claimed the quake was reminiscent of "a bomb going off".

Shelly Organ was among many residents who shared her experience on social media: "Being in Troedyrhiw we honestly thought someone had crashed into a wall so we checked the children were still sleeping and went out to check and there were a few in the street thinking the same."

Katy Alexandra Jack tweeted: "Imagine, I just felt this all the way in Dudley, West Midlands."

The BGS said the earthquake was 1.8 miles under the Earth's surface.

The largest earthquake ever recorded in the UK was in the North Sea on 7 June 1931, with a magnitude of 6.1. The epicentre was in the Dogger Bank area, 75 miles north-east of Great Yarmouth, Norfolk.

Wales's most powerful quake was on the Llŷn peninsula, Gwynedd, in 1984 - measuring 5.4, it began at a depth of more than 12 miles.

The BGS said smaller quakes were not unusual in Wales, which has had 70 measuring more than 3.5 between 1727 and 1984.
