Only one historical eruption is known from Burney, which occurred in 1910. This eruption has a volcanic explosivity index of 2, and was observed by a merchant ship. This eruption appeared to coincide with an earthquake and tsunami on 24 June 1910 in the area. An unconfirmed report of an eruption in 1920 exists, as well as reports of a flash of light and earthquakes during the night of 24 June 1970. No reports of such activity were identified in the contemporaneous newspaper La Prensa Austral, however. Shallow seismic activity occurs to this day at Monte Burney.
