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.
