An earthquake measuring 0.4 on the Richter scale has been recorded off the north west coast of Wales, according to the British Geological Survey (BGS). The tremor occurred at 7.55am on Sunday, November 2, with its epicentre located 5.6 miles southwest of Rhosneigr in the Irish Sea, at a depth of 17km. The BGS has reported no significant impacts on land following this minor quake. Northwest Wales is known for its seismic activity, having experienced several tremors this year. In July, a smaller 0.2-magnitude quake was detected 9.9 miles northeast of Amlwch, Anglesey. The following month, a more substantial 1.6-magnitude event struck the Gwynedd village of Llwyndyrus on the Llŷn Peninsula. Additionally, a 0.7-magnitude tremor was recorded in September in Bannau Brycheiniog National Park at Llangyndir. Powys has been particularly active, with at least six tremors reported in the county over the past three months. In a separate incident, a 3.3-magnitude earthquake was felt in parts of Perth and Kinross, Scotland, on Monday, October 30. The BGS noted that this quake began at 7.25am, with its epicentre in Pubil, located in the Glen Lyon region. Reports from residents and visitors in the area indicated they felt the tremor. Scientists have long studied potential connections between solar activity and seismic events. Recently, a series of solar flares resulted in two geomagnetic storms, with the second storm being a significant "cannibal storm"—one of the largest solar storms in the past two decades. There is speculation that geomagnetic storms may increase pressure on the Earth’s magnetosphere, potentially leading to surface compression that could trigger earthquakes between tectonic plates. While a direct link remains unproven, researchers are optimistic that analysing solar activity could enhance earthquake prediction models. A 2022 study from Japan suggested a possible causal relationship between sunspot activity and seismic patterns. A follow-up study published this year indicated that solar heating of the Earth’s surface might influence rock properties and underground water movement, possibly contributing to earthquake activity. Although solar activity is unlikely to be the primary cause of seismic events, incorporating this data into Earth temperature models may improve the accuracy of future earthquake forecasts.
