The volcano was active in the Quaternary period, from 2.5 million years ago to the present.[lower-alpha 1] Radiometric dating has yielded ages of up to 300,000 years for its rocks, and it reached its present height about 200,000 years ago. Several tephra layers encountered in ice cores at Mount Waesche and Byrd Station have been attributed to Mount Takahe, although some of them were later linked to eruptions of Mount Berlin instead. The tephra layers were formed by explosive or phreatomagmatic eruptions.
