Volcanic Eifel

Tephra layers in a quarry near Weibern in the Brohl Valley.

The Volcanic Eifel or Vulkan Eifel (

volcanic geological history. Characteristic of this volcanic field are its typical explosion crater lakes or maars, and numerous other signs of volcanic activity such as volcanic tuffs, lava streams and volcanic craters like 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

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 (
Hillesheim (within the parish of Nohn
),

Volcanic High Eifel (

Ulmen

and Nohn),

Volcanic East Eifel (Brohltal, Vordereifel, Mendig, Pellenz)

The centre of the Volcanic Eifel is the region around Daun and Manderscheid and the areas within the

Mayen-Koblenz district

.

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 2,000 km² (770 sq mi) and as of 2007^[update] has a population of about 200,000.

Future activity

There is thought that future eruptions may occur in the Eifel, as:[3]^[4]

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.

In 2020, Professor Kreemer noted that Eifel was the only region within an area of Europe studied where

magma plume.^[5] This activity does not imply an immediate eruptive danger, but might suggest an increase in volcanic and seismic activity in the region.^[5]
