An earthquake felt across Pembrokeshire this afternoon (Saturday) is reportedly the biggest experienced in the UK for a decade.
A two-second tremor was felt by people across England and Wales as scientists confirmed a reading of between 4.4 and 4.9 on the Richter scale.
Thousands took to social media to share their experience after the mini-quake happened at 2.31pm, with residents from all over the county reporting a loud rumble and feeling the ground shake.
Anita Buxton from Mynachlog-Ddu posted on a Facebook group: “It lasted several seconds and rumbled....it made the house shake.”
Jan Doherty of Crymych said the quake sounded like heavy machinery passing and rattling the windows.”
Christine Williams said: “I felt it here in St Davids - thought I was going mad - glasses rattled in the dishwasher - wondered if the house was haunted!”
Daniel Browne added: “Felt it in Pembroke Dock thought the ferry had crashed or refinery had exploded very scary.”
Reports suggest it was felt in south Wales, south-west England, the West Midlands and North West.
Scientists at the European-Mediterranean Seismological Centre (EMSC) described it as a ‘strong earthquake’ and said south Wales was the epicentre.
Dyfed-Powys Police stated they received an ‘extremely high’ volume of calls reporting an earth tremor in the area.
The force tweeted: “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.”
The British Geological Survey is in the process of analysing data for the tremor.
