A 4.4 magnitude earthquake has hit western Britain, something that only happens every two to three years.
The British Geological Survey said it was analysing the data recorded by its real-time seismogram monitoring station in Monmouth.
The quake had a magnitude of 4.4 and its epicentre was 10km north east of Swansea, according to monitors EMSC.
The British Geological Survey said a quake of this size happened in Britain only once every two or three years.
Just in: Event epicentre approx 20km NNE of Swansea, with 4.4 magnitude at a depth of 7.4km. Events of this magnitude only happen in the UK every 2-3 years.
This British Geological Survey real-time seismogram monitoring station at Monmouth recorded an earthquake that’s widely being reported on Twitter across Wales, SW & NW England, parts of the Midlands.@BritGeoSurvey are currently analysing the data, with more info to follow soon. pic.twitter.com/2iEu0k1KUJ— Liam Dutton – Weatherman (@liamdutton) February 17, 2018
We are in the process of analysing data for the felt report of a tremor in the SW of England. As soon as we know more we’ll let you know.
We felt the #earthquake here at Met Office HQ too. If you have any further enquires please get in contact with @BritGeoSurvey https://t.co/Tc9zFoYp7F

Dyfed Powys Police said it was getting “an extremely high call volume” about the tremor but told people: “There is nothing to worry about.”
We are receiving an extremely high call volume reporting some sort of earth tremor in the area – we are receiving reports from across the whole of Wales (we felt it in our control room too!). For now – it is unexplained – but there is nothing to worry about.

HuffPost UK reporter Kathryn Snowdon was in a cafe in Swansea city centre at the time the earthquake struck.
She said: “It suddenly felt as though the whole building was shaking for a few seconds. It was scary at first but it was over with so quickly that no-one was really sure what had just happened.
“Some thought it was just very windy outside and others thought that a large vehicle was passing nearby.
“It wasn’t until we started searching on social media that it became clear it was felt across the rest of south Wales and England.
“There aren’t any signs of damage and people look to be carrying on as normal.”
Rory Castle Jones, who lives in Craig-Cefn-Parc, just outside Swansea, told HuffPost UK: “We felt the house shake and heard a rumbling. I’ve never experienced an earthquake before and had no idea what it was.
“We thought maybe it was a mine shaft collapsing or something.”
Emily Perkins, who lives in Bristol, said: “I was at home in our flat just around the corner from Temple Meads, and the whole building shook – far more than you’d expect from a heavy lorry or a freight train.
“It felt like the whole building was pushed to the side, with mirrors shaking. There isn’t any damage in the area that we can see, but I wouldn’t be surprised if some buildings have structural issues discovered later.”
