There are no longer any fire-breathing mountains in the Eifel,

but this has not always been the case. In the Tertiary period, around 45 to 35 million years ago, there were active volcanoes here. Around 1,000,000 years ago a new volcanic phase began. This ended with the most recent eruption 10,000 years ago, a blink of an eye for geologists.

In the Vulkaneifel, 350 eruptions have been recorded, of which 270 were in the most recent phase. Are further volcanic eruptions possible? Yes. The earth beneath the Eifel is moving. Ever year the Eifel rises by around a millimetre. There are innumerable points on the surface where carbon dioxide comes out or disperses in water in sparkling springs known as acidulous springs or Sauerbrunnen.
Geophysicists have discovered that the earth’s crust under the Eifel is considerably thinner than continental crusts usually are and this suggests that there is a hot zone under the Eifel where hot rock is rising to the surface. All of this allows us to conclude that the conditions still exist for volcanoes to form under the surface of the Eifel and that therefore volcanic activity in the Eifel is not extinct, but merely in a dormant phase. Volcanic eruptions are therefore possible. There is no need to worry, however, as the Vulkaneifel is one of the most scientifically researched volcanic regions on the planet and the measuring instruments show no current signs of danger.
