Porak or Akharbakhar ("gutted belly" in Azerbaijani^[1]) is a stratovolcano located in the Vardenis volcanic ridge. It lies about 20 km (12 mi) southeast of Lake Sevan and the volcanic field spans the border between Armenia and Azerbaijan with lava flows running into both countries. Ten satellite cones and fissure vents lie on the flanks of the volcano.^[2]

The Porak volcano itself and the third stage has been dated 15 ± 15 ka by K-Ar dating.^[1] Two long lava flows, one of which 21 km long, stretch from the field north and northeastwards. There are thermal springs in the area, and the Middle Pleistocene Khonarassar fault area lies to the north of the Porak centre.^[3]^[4] The Karkar volcanoes are situated in the same region.^[5] The complex is built on partly sedimentary rock and partly volcanogenic Late Cretaceous and Eocene series with Paleogene intrusions.^[1]
