An earthquake off North Wales early on Wednesday has been felt across an area more than 100km wide, the British Geological Survey (BGS) says.
The 3.8 magnitude quake had its epicentre in the Irish Sea 15km from Abersoch, Gwnedd, and was felt as far away as Southport in Merseyside, the Survey said.
The tremor at around 4.15 am sparked more than 100 reports from people who felt it, the majority within a 100km radius.
"This was a larger than average earthquake, we get around one a year of this size," the BGS said.
"People have reported hearing an initial loud banging, followed by rumbling, and intense shaking."
