Porak

Volcanic field · Armenia-Azerbaijan · 3029m

A lava flow extends across the foreground from a cone within the Porak volcanic field, located along the Vardeniss volcanic ridge about 20 km SE of Lake Sevan. The volcanic field straddles the Armenia/Azerbaijan border, and lava flows extend into both countries. This lava flow is the youngest of the volcanic field. Another flow from the same cone (located in Armenia) flowed into Lake Alagyol in Azerbaijan. Archaeological and historical evidence indicates several eruptions occurred during the Holocene.

Geological summary

The mid-Pleistocene Porak volcano lies in the Vardenis volcanic highland about 20 km SE of Lake Sevan. The volcanic field straddles the Armenia/Azerbaijan border, and lava flows extend into both countries. The flanks contain 10 satellitic cones and fissure vents. It was constructed along the active Pambak-Sevan strike-slip fault, which has bisected the mid-Pleistocene Khonarassar volcano, separating its two halves by about 800 m. Two large lava flows traveled up to 21 km north and NW, and fresh-looking lava flows form peninsulas extending into Lake Alagyol. Fifth century BCE petroglyphs were interpreted to depict volcanic eruptions (Karakhanian et al., 2002). Porak is referred to in a cuneiform inscription as Mount Bamni, and stratigraphic and archeological evidence indicates that an explosive eruption also producing a lava flow occurred at the time of a military battle dated to 782-773 BCE.

From Wikipedia

Porak or Akharbakhar 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.
