09/1993 (BGVN 18:09) Fumarolic and solfataric activity

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

Information Contacts: M. Petit-Breuilh and G. Fuentealba, Univ de La Frontera.

11/1993 (BGVN 18:11) Active fumaroles, some issuing from a hole in the snow-and-ice cap

Aerial observations on 21 September 1993 provided a clearer overview of fumarole locations. The aerial observations took place at noon and 1700 and included photo and video records. Two main vent areas were recognized and described. One vent area lies at the S side of the upper ridge segment, and covers an approximate area of 0.05-0.2 km2. This area resembled the flanks of a dome and emitted yellow-colored steam. The other vent area lies ~2 km to the NNE of the previously described one, and exits through a 100-m-wide perforation through Yanteles snow-and-ice cap. This vent area emitted a roughly 100-m high, white-to-yellow plume. Neither this vent area nor any other site in vicinity of the ridge has the morphology of a crater.

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 from Yanteles volcano. Historical activity from this 2042-m-high, andesitic volcanic complex is uncertain. Although there were reports of an eruption from Yanteles at the time of the February 20, 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.

The elongated, glacier-covered massif near the center of this NASA International Space Station image (with north to the left) is Yanteles volcano in southern Chile. The volcano is composed of five glacier-capped peaks along an 8-km-long NE-trending ridge. Historical eruptions from this 2042-m-high, andesitic volcanic complex are uncertain.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
