The last time that volcanoes were active in what is now the United Kingdom was the early Palaeogene period, just over 50 million years ago (Ma), associated with the opening of the Atlantic Ocean. Modern day hills and mountains within the UK which are sometimes described as extinct volcanoes are usually the deeply eroded roots of volcanoes ...
The Borrowdale Volcanic Group is a group of igneous rock formations named after the Borrowdale area of the Lake District, in England. They are Caradocian (late Ordovician) in age (roughly 450 million years old). [1] It is thought that they represent the remains of a volcanic island arc, approximately similar to the island arcs of the west ...
In the early Cambrian period, the volcanoes and mountains of England and Wales were eroded as the land became flooded by a rise in sea level, and new layers of sediment were laid down. Much of central England formed a stable block of crust, which has remained largely undeformed ever since. Sandstones were deposited in the north of Scotland.
Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times.

The volcano is an example of a piecemeal caldera whose collapse, in contrast with a wholesale piston-like subsidence, occurred in a piece-by-piece fashion along faults and whose measurements suggest formation from an eruption of a VEI-7 magnitude, comparable to the Minoan eruption at Santorini in the Greek Aegean in c. 1600 BCE.
The geology of England is mainly sedimentary. The youngest rocks are in the south east around London , progressing in age in a north westerly direction. [ 1 ] The Tees–Exe line marks the division between younger, softer and low-lying rocks in the south east and the generally older and harder rocks of the north and west which give rise to ...
