Taftan is a strongly eroded andesitic stratovolcano with two prominent summits. The volcano was constructed along a volcanic zone in Beluchistan, SE Iran, that extends into northern Pakistan. The higher, 3940-m SE summit cone is well preserved and has been the source of very fresh-looking lava flows. Highly active, sulfur-encrusted fumaroles occur at the summit of the SE cone. The deeply dissected NW cone is of Pleistocene age. In January 1902 the volcano was reported to be smoking heavily for several days, with occasional strong night-time glow. A lava flow was reported at Taftan in 1993, but may have been a mistaken observation of a molten sulfur flow.
