Potassium-argon dating of Balagan-Tas has yielded an age of 266,000 ± 30,000 years ago, comparable to Anyuj volcano. Other sources consider the volcano late Holocene in age, or even as active during historical time. Hot springs are found southeast of Balagan-Tas. They reach temperatures of , which together with the other activity indicates a hot upper mantle. If reports of activity of the supposed Indighirsky volcano in the 1770s refer to Balagan-Tas, this volcano may have had historical activity, one of the few outside of Kamchatka in continental Asia.
