The Todra volcanic field covers a broad area of about 1050 sq km in the Tuareg shield in the southern Aïr region of Niger. Activity began with the eruption of about 30 trachytic and phonolitic volcanoes through Precambrian basement rocks. This was followed by the formation of about 130 basaltic cones that typically produced a valley filling lava flow. A series of NW-SE-trending faults control volcano locations. The date of the latest eruption of the Todra volcanic field is not known, but may have been as recent as a few centuries ago.

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

This small Aïr basaltic cinder cone and blocky lava flow is part of the Todra volcanic field, which covers a broad area of about 1050 sq km in the Tuareg shield in the southern Aïr region of Niger. Construction of about 30 trachytic and phonolitic volcanoes was followed by the formation of about 130 basaltic cones. The date of the latest eruption of the Todra volcanic field is not known, but may have been as recent as a few centuries ago.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
