Todra volcanic field is a volcanic field in the Aïr region, Niger.
The field consists of about 150 volcanoes, whose position is fault controlled. Their eruption products (mainly basalt but also phonolite and trachyte) cover a surface of about 1,050 square kilometres (410 sq mi). [1] Geologically, they are located at the northwestern end of the Téfidet graben of the Trans-Saharan orogen. [2]
The field may have had historical eruptions. [1]
