The mighty Niesen supervolcano, deep in the Berner Oberland

The central mountainous region of Switzerland is known as the Berner Oberland, and it contains a danger so frightening that most scientists are reluctant to discuss it at all.

For here is a breathtaking view of none other than the Niesen Supervolcano:

There are around 9 supervolcanos in the world, and an eruption by any one of them would permanently change the face of the planet.

Scientists and geologists universally agree that when (not if) the Niesen Supervolcano erupts, all life in Europe will be extinguished.
