Geography
Geologically, the feature is most likely a moraine, formed during the Pleistocene. At differing times during the last ice age it was land joined to the mainland, or an island. Fishing trawlers working the area have dredged up large amounts of moor peat, remains of mammoth and rhinoceros, and occasionally Paleolithic hunting artefacts. The bank was part of a large landmass, known as Doggerland, which connected Britain to the European mainland until it was flooded some time after the end of the last ice age.
In 1931, the largest earthquake ever recorded in the United Kingdom took place below the bank, measuring 6.1 on the Richter scale. Its focus was 23 km beneath the bank, and the quake was felt in countries all around the North Sea, causing damage across eastern England.
