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 2,000 km². Its glacially dissected surface is cut by broad valleys and contains several table-like mountains composed of hyaloclastites and lava flows, and has numerous small scoria cones. The Shivit-Tayga stratovolcano is one of the most prominent features of the plateau and is capped by two craters that once contained lava lakes. Derbi-Tayga is glacially eroded shield volcano. The surface of the Ulug-Arginsky cinder cone, initially considered to be Holocene, has large granitic erratics and was given a late-Pleistocene age by Hasenaka et al. (1999). Some valley filling basaltic flows are not glacially eroded and have a Holocene morphology. Well-preserved lava flows near the Bii-Hem River may be of Holocene age.

Eruptive History

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 12,000 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).

Deformation History

There is no Deformation History data available for Azas Plateau.

Emission History

There is no Emissions History data available for Azas Plateau.

Photo Gallery

The Ulug-Arginsky scoria cone, seen here from the north in the sunlight in the center, is part of the Azas Plateau volcanic field west of the SW tip of Lake Baikal. Large granitic erratics (boulders emplaced by glaciers) were deposited on the surface, and lava flows from the cone are glacially eroded and overlain by moraines. The Azas Plateau volcanic field covers an area of about 1,500 km². Some basaltic lava flows in broad glacially carved valleys are unglaciated and of probable Holocene age.

Reddish scoria and ash forms the surface of the Ulug-Arginsky scoria cone, located about 200 km WNW of the SW tip of Lake Baikal. The red color is from oxidation when the clasts were erupted at high temperatures.

The Copernicus Browser replaced the Sentinel Hub Playground browser in 2023, to provide access to Earth observation archives from the Copernicus Data Space Ecosystem, the main distribution platform for data from the EU Copernicus missions.

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.

MODVOLC Thermal Alerts

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.

WOVOdat
   Single Volcano View
   Temporal Evolution of Unrest
   Side by Side Volcanoes

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.

Volcanic Hazard Maps

The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter.

Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice.

Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player.

DECADE Data

The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the Mapping Gas Emissions (MaGa) Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO₂ to the atmosphere, but installing CO₂ monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere.

Large Eruptions of Azas Plateau

Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
