Geological Summary

Tarso Toussidé, a broad volcanic massif at the western end of the Tibesti Range, is capped by the Toussidé stratovolcano, constructed at the western end of the 14-km-wide ignimbritic Yirrigue caldera of Pleistocene age. The 6000 km² massif was constructed over a basement of Precambrian schists on the east and Paleozoic sandstones on the west. The summit contains numerous fumaroles and very youthful lava flows that would be of historical age in an inhabited region (Vincent 1992, pers. comm.). Fresh-looking trachytic and trachyandesitic lava flows cover an area of 200 km² and extend as far as 25 km from the summit on the western side. The steep-sided, 1-km-deep, 8-km-wide Trou au Natron caldera cuts the SE rim of Yirrigue caldera and is one of the youngeset features of the massif. Ehi Timi and Ehi Sosso volcanoes and the smaller 1.5-km-wide explosion crater of Doon Kidimi are located on the NE-to-ESE flanks of the massif.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Tarso Toussidé. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Tarso Toussidé 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 Tarso Toussidé.

Emission History

There is no Emissions History data available for Tarso Toussidé.

Dark lava flows radiate from Toussidé volcano (center), the second highest peak of the Tibesti Range in Chad. N to the bottom of this Space Shuttle image. It was constructed at the W end of the large Pleistocene caldera of Yirrigue, whose scarp is seen left of Toussidé. The smaller 8-km-wide caldera of Trou au Natron cuts the SE rim of the caldera. Ehi Timi (lower center) and Ehi Sosso (left center) volcanoes are located on the flanks of the massif.

A dramatic Space Shuttle image shows dark lava flows radiating from Toussidé volcano and spreading across the desert floor. Light-colored altered areas can be seen at the summit, the second highest peak of the Tibesti Range in Chad. It was constructed at the W end of the large Pleistocene caldera of Yirrigue, whose E scarp is seen right of Toussidé. The smaller 1-km-deep, 8-km-wide Trou au Natron caldera (lower right) cuts the SE rim of the caldera.

Tarso Toussidé is a nested caldera system in the Tibesti massif in Chad, seen in this November 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 44 km across). Trou au Natron is the caldera along the SE boundary, the crater to the NNE is Petit Trou/Doon Kidimi. The long, narrow lava flow to the NW is one of the more recent eruptive products.

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.

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 Tarso Toussidé

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).
