The UK experienced an unusually high number of earthquakes in 2025, with over 300 tremors recorded across the country, according to data from the British Geological Survey (BGS).
UK Earthquake Activity in 2025
The two largest earthquakes occurred within hours of each other near Loch Lyon in Perth and Kinross, Scotland, on October 20th. A 3.7 magnitude tremor was followed by a 3.6 magnitude quake.
Up to December 18, 2025, a total of 309 earthquakes had been recorded. The most significant seismic activity was observed in areas of Perthshire and the western Highlands in Scotland, southern Wales, and the English counties of Yorkshire and Lancashire.
Seismologist Brian Baptie stated that the UK experienced an earthquake “almost once a day” throughout 2025. The BGS monitors seismic activity through 80 stations across the UK.
Between October and December, 34 earthquakes were detected near Loch Lyon. Dr. Baptie noted that the west of Scotland is a particularly active seismic region, due to geological faults including the Great Glen and the Highland Boundary Fault.
In December, two minor earthquakes struck Lancashire in as many weeks. A 2.5 magnitude tremor, with its epicenter off the coast of Silverdale in Morecambe Bay, was confirmed as an aftershock of a 3.3 magnitude earthquake earlier in the month.
The UK typically experiences between 200 and 300 earthquakes annually, though most are not felt or heard by the public. In 2025, the BGS received 1,320 reports from members of the public who felt tremors.
Earthquakes of magnitude four occur in the UK and surrounding areas roughly every three to four years, while magnitude-five events are less frequent, occurring every few decades. The most recent magnitude-five earthquake occurred in 2008 in Lincolnshire.
A magnitude-six earthquake happens every few hundred years. The largest known earthquake in the UK, with a magnitude of 6.1, occurred in 1931 near Dogger Bank in the North Sea, off the coast of Yorkshire. Despite being 60 miles offshore, it caused minor damage to buildings on the east coast of England.
Earthquakes are generally caused by the movement and friction of tectonic plates. Smaller earthquakes, like those experienced in the UK, are often triggered by movements on geological faults within the Earth’s crust. The UK is located within the Eurasian plate, over 1,000 miles from the nearest plate boundary, which explains why it does not experience earthquakes as large as those in other parts of the world.
