The Eifel hotspot is a volcanic area sometimes categorised as a "hotspot" in Western Germany. It is one of many recent volcanic formations in and around the Eifel mountain range, especially the volcanic field known as Volcanic Eifel. Although the last eruption occurred around 10,000 years ago, the presence of escaping volcanic gases in the region indicates that it is still active, if only weakly. A seismic anomaly has been observed in the upper mantle beneath the Eifel volcanic area and interpreted as indicating the presence of a mantle plume[1] which, on the basis of large-scale uplift and extension of the Earth's surface above the putative plume, is thought to be actively buoyant[2]. Several observations, however, do not fit the plume hypothesis and indicate instead that volcanic activity in this area is a result of passive melting due to lithospheric/crustal extension and shallow convective processes related to the subduction of the Eurasian plate during the Alpine orogeny[3][4][5].
