Aguilera erupted during the Holocene, depositing tephra in the region of Lago Argentino and Torres del Paine. The composition of rocks erupted by Aguilera are similar to these from Lautaro and Viedma, and the linkage of specific ash deposits to Aguilera is based mainly on geographical considerations. Other volcanoes have left tephra deposits in the wider region, including Cerro Hudson, Monte Burney and Reclus.
