Süphan Dagi is a 4158-m-high basaltic-to-rhyolitic stratovolcano located immediately north of Lake Van. A glacial icecap mantles the summit of the volcano, the 2nd highest in Turkey. During construction of the volcano andesitic-dacitic lava flows alternated with fluid basaltic flows, followed by construction of a large lava dome over the central vent. The flanks of the volcano are dotted with numerous lava domes and pyroclastic cones erupted along radial and circumferential fissures, particularly on the northern, souther, and eastern sides. The 1.5-km-wide, low-rimmed Aygirgölü maar was erupted on the lower southern flank. During the latest stage of activity, voluminous basaltic lava flows traveled as far as 30 km from the summit. Potassium-Argon dates for Süphan Dagi range from 2 to about 0.1 million years, but the latest basaltic eruption occurred about 10,000 years ago (Yilmaz et al., 1998).

Snow-capped Süphan Dagi volcano rises above the NW shore of Lake Van in this Space Shuttle view with north to the upper left. The 4158-m-high basaltic-to-rhyolitic stratovolcano is the 2nd highest in Turkey. The flanks of the volcano are dotted with numerous lava domes and pyroclastic cones erupted along radial and circumferential fissures. The small black lake halfway between the snow line and Lake Van is the 1.5-km-wide Aygirgölü maar; the larger greenish Lake Arin is visible to the east.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
