Fieldwork on 7 September 1992 revealed solfataric activity consisting of steam and sulfurous gas emissions. Only steam was observed on 14 September 1993.

Geologic Background. Little-known Yanteles volcano in southern Chile is composed of five glacier-capped peaks along an 8-km-long NE-trending ridge. Several Holocene tephra layers have been documented, but historical activity from this 2042-m-high, andesitic volcanic complex is uncertain. Although there were reports of an eruption at the time of the 20 February 1835 Chile earthquake, and Sapper (1917) reported that previously unseen black areas were seen near the crater after the 1835 earthquake, the nature of this activity is not clear.
