Location

Vakak (or Wakak) volcano is a field of 18 small volcanoes 115 km WSW of Kabul. It is the northernmost of a group of small volcanic fields in the Ghanzi region and consists of lava domes, one of which occupies an old caldera.
The age of its last eruption is unknown, but could be relatively recent (less than 10,000 years ago).

Introduction:

The Vakak volcanic group is located on an intraplate hot spot, which is antipodal to the Easter Island hot spot. It has been suggested that such hot spot pairs have formed in the history of the earth by oceanic large-body impacts, triggering flood basalt eruptions at the impact site and (minor) hot spot activity at the opposite (antipodal) location on the earth's sphere.
