Ancient volcanic discovery in eastern England

Overview

Geologists have identified an ancient volcanic structure located off the eastern coast of England, near The Wash and the counties of Norfolk and Lincolnshire. By analyzing zircon crystals containing uranium isotopes, researchers determined that eruptions occurred approximately 454.4 million years ago during the Ordovician period. The study indicates that volcanic ash plumes from this site traveled across the Tornquist Sea to deposit layers in Scandinavia.

Subsequent descriptions of the event by the British Geological Survey characterize it as a highly explosive ‘super-Plinian’ eruption that ejected hundreds of cubic kilometers of rock into the stratosphere. While some researchers have used the term ‘supervolcano’ to describe the scale of the historical activity, the discovery primarily provides new insights into the geological history of the North Sea region.
