Overview
- At least 309 earthquakes were recorded across the UK in 2025, an above-average tally that equates to roughly one event per day, according to the British Geological Survey.
- The strongest onshore tremors struck near Loch Lyon on 20 October at magnitudes 3.7 and 3.6, part of a local sequence that produced 34 events between October and December.
- Perthshire and the western Highlands were most active, with notable activity also in southern Wales, Yorkshire and Lancashire, including a 3.2 quake at Silverdale on 3 December that drew nearly 700 felt reports.
- The dataset was captured by a national network of about 80 monitoring stations and supplemented by 1,320 public reports submitted to the BGS this year.
- The BGS notes typical recurrence of magnitude‑4 events every three to four years, magnitude‑5 every few decades and magnitude‑6 every few hundred years, stressing that tracking small tremors helps assess risks to energy and infrastructure projects.
