Stephen Hicks, Earth Scientist at the University of Southampton, said such activity can be expected in the region at least once every eight years. “On average, the UK typically experiences one similar-sized earthquake every 2-8 years,” he said.
Tremors were felt from Swansea to cities closer to the east coast of the United Kingdom. A number of people took to social media to recount their experience of the quake. Parts of Swansea University campus were evacuated as a precaution.

Did anyone else feel the earth move about 5 mins ago? Definitely a tremor here in Liverpool. I’m in a flat and it made a weird noise and moved from side to side for about ten seconds. #earthquake#tremor
