Britain was hit by its biggest earthquake in a decade Saturday, the British Geological Survey (BGS) said, with tremors felt across parts of Wales and southwest England but no notable damage reported.
The BGS said the quake was of magnitude 4.4, with an epicenter 20 km (12.5 miles) north of the Welsh city of Swansea, adding that it was the biggest quake in the Britain since 2008.
Earthquakes are not common in Britain and are rarely powerful. The 2008 quake in Market Rasen, northeast England, was magnitude 5.2, or 16 times more powerful than Saturday’s quake.
However, Saturday’s earthquake in Wales was felt as far away as Carisbrooke Castle on the Isle of Wight, more than 200 km (125 miles) away.
Videos on social media showed people gathered outside Swansea University, which was holding an open day, after an apparent evacuation.
“Thank you to everyone who attended our visit day. We hoped that you had a surprisingly ‘earth moving’ experience!” Swansea University said on Twitter.
