Geologic Background:
Yanteles sits directly on the continental margin
in Chile's archipelago region. Ths stratovolcano with a
summit elevation of Å2,050 m, is located 275 km north of
Hudson volcano. Its nearest volcanic neighbor, Corcovado,
sits 30 km to the north. This little-known volcano in
southern Chile is composed of five peaks along an
8-km-long NE-trending ridge.
Historic Activity:
- The only known historical activity was a Strombolian
eruption on Feb. 20, 1835 that ejected ash and lapilli
from an explosion vent on the flank of the crater.
Increased snow-melt in 1835 may have been caused by
increased thermal activity.
Recent Activity:
- Solfataric activity consisting of steam and sulfurous
gas emissions. Two main vent areas.
Data Sources:
- Global Volcanism Network (V. 18, No. 9 to V. 18, No.
11).
