Geological Summary

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. Andesitic-dacitic lava flows alternated with fluid basaltic flows, followed by construction of a large lava dome over the central vent. The flanks are dotted with numerous lava domes and pyroclastic cones erupted along radial and circumferential fissures, particularly on the northern, southern, and eastern sides. Voluminous basaltic lava flows traveled as far as 30 km from the summit. Although Yilmaz et al. (1998) reported that there had been a basaltic eruption about 10,000 years ago, Ozdemir and Gulec (2013) made no mention of any activity that recent; based on previous K-Ar studies and new Ar-Ar dating work, they found an activity range of 0.76-0.06 Ma. Dacitic and rhyolitic domes in the summit crater followed all lava flows and pyroclastic deposits from the main cone, with one dated at 64 +/- 14 ka. The 1.5-km-wide, low-rimmed Aygir Gölü maar was formed on the lower S flank, and represents the most recent activity (undated), characterized by a phreatomagamtic eruption and related deposits.

The Global Volcanism Program is not aware of any Holocene eruptions from Suphan Dagi. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Suphan Dagi page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

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.
