England's Hidden Giant: A Supervolcano Unearthed
28 Aug
Summary
- A massive supervolcano, thousands of times more powerful than Mount Etna, was discovered.
- It erupted with the force of thousands of hydrogen bombs 454 million years ago.
- The volcano's ash layer is spread across parts of Northern Europe.

Deep beneath England's east coast lies the colossal remnant of a supervolcano, a geological discovery of immense significance. This ancient giant, with a diameter of at least 65km, is estimated to be thousands of times more powerful than Mount Etna. It erupted 454 million years ago with a force comparable to several thousand hydrogen bombs.
The British Geological Survey (BGS) believes this supervolcano is responsible for a massive layer of volcanic ash found spread across Norway, Sweden, the Baltic region, Belarus, and Poland. Experts hail the discovery as a fantastic result, profoundly changing our understanding of England's deep geological past.
