The Vulkan Eifel (German: Vulkaneifel) is a region in the Eifel Mountains in Germany, that is defined to a large extent by its volcanic geological history. Characteristic of the Vulkan Eifel 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 Vulkan Eifel is still volcanically active today. One sign of this activity is the escaping gases, for example, in the Laacher See.
The Vulkan 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 the 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 Vulkan Eifel is divided into 3 natural regions:
The centre of the Vulkan Eifel is the region around Daun and Manderscheid and the areas within the Mayen-Koblenz district.
The landscape of the Vulkan 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 Vulkan Eifel covers an area of about 2000 km² and has a population of 200,000 (as at 2007).
