The following is a list of notable earthquakes that have been detected in the British Isles.
On average several hundred earthquakes are detected by the British Geological Survey each year, but almost all are far too faint to be felt by humans. Those that are felt generally cause very little damage.
Nonetheless, earthquakes have on occasion resulted in considerable damage, most notably in 1580 and 1884; Musson (2003) reports that there have been ten documented fatalities – six caused by falling masonry and four by building collapse.
For earthquakes prior to the modern era, the magnitude and epicentre location are only approximate, and were calculated based on available reports from the time. The magnitude where given is measured using the Richter scale .
