Porak or Akharbakhar ("gutted belly" in Azerbaijani) is a stratovolcano located in the Vardenis volcanic ridge. It lies about 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.
The Porak volcano itself and the third stage has been dated 15 ± 15 ka by K-Ar dating. The Karkar volcanoes are situated in the same region.
Khorkhor inscription
The Khorkhor inscription, in which Argishti I of Urartu records the conquest of the city of Behoura, records that during the siege the town was destroyed by an earthquake and eruption of "Mount Bamni". Historians consider it likely that Porak volcano is Mount Bamni and that Behoura was one of the archeological sites in the area.
Older evidence of volcanic activity, including lacustrine deposits, indicate temporary disappearance of forests in the area before 6,270BP, likely due to forest fires induced by volcanic activity. Petroglyphs dated about 5,000BP also portray volcanic activity, It is not entirely clear which eruption is depicted by the Porak petroglyphs.
