The Global Volcanism Program is not aware of any Holocene eruptions from Maug Islands. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Maug Islands page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Maug Islands.

Photo Gallery


An aerial view of the Maug Islands from the NE shows Kita-shima (North Island) at the right margin, Higashi-shima (East Island) in the foreground, and Nishi-shima (West Island) in the background. The islands enclose a 2.5-km-wide submarine caldera that contains a submerged lava dome that rises to within about 20 m of the sea surface. No eruptions are known from the Maug Islands since their discovery by Espinosa in 1522.
