Volcanic Eifel
The Volcanic Eifel or Vulkan Eifel consists of three areas of volcanic activity, known as the West Eifel, High Eifel, and East Eifel volcanic fields. Volcanic Eifel is a region in the Eifel Mountains in Germany that is defined to a large extent by its volcanic geological history. Characteristic of the volcanic fields are their typical explosion crater lakes or maars, and numerous other signs of volcanic activity such as volcanic tuffs, lava streams and volcanic craters, for example the Laacher See. The Volcanic Eifel is still volcanically active today. One sign of this activity is the escaping gases in the Laacher See.
Geographical location
The Volcanic Eifel stretches from the Rhine to the Wittlich Depression. It is bordered in the south and southwest by the South Eifel, in the west by Luxembourg and Belgian Ardennes and in the north by the North Eifel including the Hohes Venn. To the east the Rhine forms its geographical boundary, with no volcanicity immediately beyond it.The Volcanic Eifel is divided into three natural regions:
- Volcanic West Eifel : Manderscheid, Daun, Gerolstein, Obere Kyll, Hillesheim
- Volcanic High Eifel :
- Volcanic East Eifel :
The landscape of the Volcanic Eifel is dominated by recent volcanism. Volcanic craters, thick pumice and basalt layers and maars create a diverse landscape that clearly witnesses to very recent events in geological terms.
The entire Volcanic Eifel covers an area of about and as of 2007 has a population of about 200,000.

Laacher See
Of particular note is the volcanic caldera known as Laacher See, the site of an eruption around 12,900 years ago that had an estimated VEI of 6.Geopark and museums

Geology
The tephras deposited by past eruptions of the Volcanic Eifel are lithological deposits that are radiometrically dateable via argon-argon dating of K-feldspar grains. These have in turn been utilised to ascertain the ages of climatic changes such as transitions from glacial to interglacial states during the Pleistocene.Future activity
There is thought that future eruptions may occur in the Eifel, because:- Each year the Eifel rises by about a millimetre.
- Geophysicists found that crust under the Eifel is thinner than most continental crust, suggesting that under the Eifel is a hot zone where magma is rising.
- Persistent small earthquakes and underground heating.
