The largest earthquake with the highest recorded magnitude equal to 6.1 in the history of the Great Britain is that which it faced nearby the Dogger Bank in the year 1931. It did not prove to be that disastrous as it was 60 miles offshore. However, its impact was visible as some buildings on the east coast of England did get damaged to a small extent.

A more serious damage was faced by UK in the year 1884 in Colchester area when about 1200 buildings got influenced by the earthquake and demonstrated the need for repairing collapsed chimneys and cracked walls. (British Geological Survey, 2014)
Derbyshire warns in his online article published on “daily mail” (2010) that UK has a big earthquake threat that might occur anytime and cause hundreds of people to die. It is due to the movement of a fault in the inside layer of earth that resulted in an earthquake measured at a value of 6.0 on the rector scale back in 1580. It killed 2 children in that year but today when it is expected to happen again, the population has grown up to 50 times more than what it was five hundred years back and therefore it can have much more devastating consequences. Though, it is unpredictable that when and where the next earthquake might occur, the small city of London with dense population and residential units in the Thames valley are most susceptible to catastrophic damage as the foundations of the buildings at these places is laid on soft clay which goes through greater movement in an earthquake situation in comparison to those buildings that are built on hard rock.
Recently, on August 14, 2014, BGS recorded minor jerks of earthquake (magnitude = 1.3 to 1.7) in the Askern, South Yorkshire Region around the British Isles. Furthermore, BGS is of the view that the largest possible earthquake that might take place in UK is expected to be as big as a measurement of 6.5 on Richter scale and this can cause serious damage such that it can uproot the older buildings.
