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.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
