Geological summary
Aguilera, located west of Lake Argentina and NE of Peel Fjord, is part of the Austral Volcanic Zone (AVZ) in the southernmost Chilean Andes. Geochemical evidence indicated that the dacitic volcano was the source of a major late Holocene tephra layer that was erupted around 3,200 years ago (Stern, 2008).
Separate activity dataset
Weekly volcanic activity reports
Smithsonian/USGS weekly reports are selective and preliminary. They are not a comprehensive list of all eruptions or volcanic activity.
No weekly report appears on this page. Absence from the weekly report does not establish an absence of volcanic activity.
