A 1.6-magnitude earthquake occurred on the Llŷn Peninsula in Gwynedd, North Wales, with its centre in the hamlet of Llwyndyrus. The British Geological Survey recorded the tremor at 1.6 on the Richter scale. Residents reported a long steady rumble, some vibration, and creaking houses, with people in Cwm-y-glo, Llanberis, Waunfawr and surrounding areas feeling the effects and some rushing outside. The Llŷn Peninsula has logged approximately 300 tremors since 1970 and ranks among the UK's ten most active earthquake zones. Northwest Wales has a documented history of notable earthquakes, including a 5.4 event in July 1884.
The earthquake struck the Llŷn Peninsula in Gwynedd, North Wales, rattling houses and forcing residents to flee their homes. The British Geological Survey (BGS) said the tremor on Tuesday registered 1.6 on the Richter scale. On social media, people mistook it for a sonic boom with residents saying they experienced a 'long steady rumble' and 'some vibration'. Its centre was in the small hamlet of Llwyndyrus, just miles from where the UK's largest ever recorded earthquake four decades earlier.
In July 1884, a 5.4 magnitude event was felt throughout Wales, most of England, and sections of Ireland and Scotland. It triggered rockfalls and fractured stonework with the most severe damage occurring in Liverpool 65 miles away. During the month that followed, roughly 80 aftershocks were detected, the strongest measuring 4.3 in magnitude. Northwest Wales is known for its high seismic activity. Notable earthquakes were recorded in 1852, 1903 and 1940, with smaller incidents occurring in Bangor and Anglesey in 1967 and 1969.
