Residents report houses shaking as earthquake felt in South Wales

An earthquake with a magnitude of 3.7 has shaken parts of Wales overnight.

The British Geological Survey said the quake, which had a depth of 3.6km (2.2 miles), happened at 11.59pm on Friday.

Its epicentre was Brynmawr in Blaenau Gwent – approximately 12 miles away from Merthyr Tydfil.

Residents throughout the region, mainly from within around 25 miles of the epicentre, reported the incident.

Reports described “the whole house was shaking”, “the rumbling and the bang woke me up”, “my bed seemed to move side to side”, and it “was like a large explosion”, the British Geological Survey said.

Kathryn Gower, 37, lives over 18 miles from the earthquake’s epicentre in Llanbradach, Caerphilly, and said she has never “experienced anything like this” in Wales.

“I was woken up to the bed shaking, it was a very bizarre feeling,” Ms Gower, who works in the charity sector, told the PA news agency.

“(It was) a bit unnerving.

“I felt it for a few seconds, I would say … It wasn’t loud, almost like when a large truck drives past and you get that really low distant rumble.”

People on social media described hearing a loud bumping noise before their houses shook.

BBC journalist Alex Humphreys said she had felt what appeared to be a “mini earthquake” in Cardiff.

“My whole bed shook. Felt like something hit the wall,” she tweeted.
