Overview

Little-known glacier-covered Yanteles volcano in southern Chile is at the corner of a volcanic massif located 60 km S of the city of Chaiten, with higher eroded peaks about 5 km E and along a ridge extending 10 km SW. Several Holocene tephra layers have been attributed to this volcano. There were reports of an eruption at the time of the 20 February 1835 Chile earthquake, and Sapper (1917) stated that previously unseen black areas were observed there after the 1835 earthquake, but the nature of this activity is not clear.

Regional Volcanic Activity

The South America Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

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.
