South-west and Wales shaken by ‘biggest earthquake in a decade’
People either side of the Bristol Channel said they felt the Earth move.
An earthquake which shook parts of the UK on Saturday was the biggest for a decade, experts said.
The British Geological Survey (BGS) said the epicentre was 20km (12 miles) north of Swansea, with a 4.4 magnitude at a depth of 7.4km (4.6m).
A BGS tweet added: “Around 3,000 event of this size in the world every year Biggest onshore UK event in 10 years, since 27 Feb 2008 Market Rasen eq 5.2 ml 16X bigger than today’s event”

Mark Wyatt, a third-year student at Cardiff University, was entering his house in the city centre when he heard a “weird, deep rumbling sound” at around 2.30pm.
The 21-year-old told the Press Association: “We heard the noises before we felt the rumble, and then the house shook for a couple of seconds before it stopped.”
