Geological Summary

The Azas Plateau is a large volcanic field located west of the SW tip of Lake Baikal and north of the Mongolian border. The gently sloping plateau, also known as the East Tuva Plateau, the Northeast Tuva Plateau, or the Khamsara-Biykhem Plateau, covers an area of about 2000 sq km. Its glacially dissected surface is cut by broad valleys and contains several table-like mountains composed of hyaloclastites and lava flows and dotted with small scoria cones. The 2765-m-high Shivit-Tayga stratovolcano is one of the most prominent features of the Azas Plateau and is capped by two craters that once contained lava lakes. Derbi-Tayga is a 2605-m-high glacially eroded shield volcano. The surface of the Ulug-Arginsky cinder cone, initially considered to be Holocene in age, is dotted with large granitic erratics and was considered by Hasenaka et al. (1999) to be of late-Pleistocene age. Some valley filling basaltic flows in the Azas Plateau are not glacially eroded and have a Holocene morphology. Well-preserved lava flows near the Bii-Hem River may be of Holocene age.

The Global Volcanism Program is not aware of any Holocene eruptions from Azas Plateau. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Azas Plateau 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.

Photo Gallery

The Ulug-Arginsky cinder cone, seen here from the north in the sunlight at left-center, is part of the Azas Plateau volcanic field west of the SW tip of Lake Baikal. The cone is dotted with large granitic erratics, and lava flows from the cone are glacially eroded and overlain by moraines. The Azas Plateau volcanic field, also known as the East Tuva volcanic field, covers an area of about 1500 sq km. Some basaltic lava flows in broad glacially carved valleys are unglaciated and of probable Holocene age.

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.
