Geologic Background:
Pular is believed to be Pleistocene in age. The
summit and flanks show signs of deep glacial erosion.
Pular is the northernmost member of the chain of
volcanoes that bears the same name (Cordon Pular). Cerro
Pajanales (24.20°S, 68.10°W), a satellite vent
of Pular (5 km SW of the summit) is a lava and dome
complex believed to be Quaternary in age.
Historic Activity:
- None of the chain has had historic volcanic
activity.
Recent Activity:
- Small explosion eruption on April 24, 1990 occurred
in area, source uncertain, but could have been from Cerro
Pajanales. But later reports suggest that no eruption
occurred.
Data Sources:
- Global Volcanism Network (V. 15, No. 6 and V. 16, No.
1).
