Geological summary

The Adare Peninsula is a complex of overlapping shield volcanoes forming the northernmost volcanic pile of the Hallet Volcanic Province. Hamilton (1972) considered uneroded cinder cones at Cape McCormick to be of Holocene age, but similar-looking Antarctic cones have proved to be as old as Tertiary. Most Potassium-Argon dates for the Adare Peninsula range from 6-13 million years ago (Ma), but one possibly anomalous date of 1.14 Ma was obtained, and a sample from Cape Roget was dated at 2.27 Ma (LeMasurier and Thomson, 1990).

Separate activity dataset

Weekly volcanic activity reports

Preliminary and selective

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.

Historical catalogue records

Eruption history

Dates can be approximate, incomplete, or BCE. These are historical catalogue observations, not a statement about present activity.

No historical eruption records appear on this page.
