Geological Summary

Tendürek Dagi, also known as Tendürük Dagi, is an elongated shield volcano that rises 1800 m above the plain of Dogubayazit, near the Iranian border, south of Mount Ararat. An E-W-trending summit ridge, developed north of an arcuate caldera structure exposed only on the southern side, contains two well-developed cones. The higher western cone is capped by a steep-walled crater with a trachytic spine at its eastern edge. The flatter eastern crater contains a warm lake. The shield volcano developed during a period when highly mobile lava flows from the western crater covered an area of 500 sq km. Following summit caldera formation, numerous flank eruptions took place from N-S-trending fissures, producing viscous trachytic lava domes and flows as well as fluid basaltic pahoehoe flows that extend 10-20 km to the north and south. The latest activity formed two major basaltic lava flows from large cones on the NE and SE flanks. An eruption took place from a vent on the SE flank about 2500 years ago, and a gas-and-ash eruption took place in 1855.

The dark-colored circular area above and to the right of the center of this NASA Space Shuttle image (with north to the top) is Tendürek Dagi. This elongated shield volcano rises 1800 m above the plain of Dogubayazit, near the Iranian border, NE of Lake Van (whose NE tip is at the the lower left) and south of Mount Ararat (out of view to the upper right). An eruption took place from a vent on the SE flank of Tendürek Dagi about 2500 years ago, and a gas-and-ash eruption took place in 1855.

Two circular craters lie along an E-W trend on the elongated summit ridge of Tendürek Dagi shield volcano in this NASA Landsat composite image (with north to the top). The higher western cone is capped by a steep-walled crater, and the flatter eastern crater contains a warm lake. Late-stage activity formed viscous trachytic lava domes and flows as well as fluid basaltic pahoehoe flows that extend 10-20 km to the north and south.

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.
