Porak volcano is a stratovolcano on the border between Armenia and Azerbaijan, in the Vardeniss volcanic ridge about 20 km SE of Lake Sevan.
The last eruption produced a lava flow around 773-783 AD. Petroglyphs dated to the 5th century BC likely show earlier eruptions of Porak volcano.
The known thermal areas of Jermouk and Histissou are located at 15-20 km distance from Porak volcano.

Background:

The volcanic field straddles the Armenia/Azerbaijan border, and lava flows extend into both countries. The flanks of the volcano are dotted with 10 satellitic cones and fissure vents. Porak volcano 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 from Porak volcano traveled up to 21 km north and NW, and fresh-looking lava flows form peninsulas extending into Lake Alagyol.
Porak volcano is referred to in a famous 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 BC.
