The 11 x 19 km Peter I Island in the Bellingshausen Sea opposite Ellsworth Land is a morphologically youthful shield-like volcano. A 100-m-wide circular crater is found at the summit of the 1750-m-high volcano. The island was discovered by the Russian explorer Bellingshausen in 1821, and extensive summer pack ice and its isolated location far from regular shipping lanes have restricted visits to the island. Dated samples from Peter I Island range from 0.35 to 0.1 million years old (Prestvik et al. 1990). The unmodified volcanic form of the upper part of the volcano argues that parts of it may be Holocene or even historical in age (LeMasurier and Thomson 1990).

The Global Volcanism Program is not aware of any Holocene eruptions from Peter I Island. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Peter I Island 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 Peter I Island.

Peter I Island, located in the Bellingshausen Sea opposite Ellsworth Land, is seen here from the north showing Lars Christiansen Peak. The morphologically youthful shield-like volcano has an abrupt coastline and is more dissected on the northern side, with a broad, gentle slope to the south. The island was discovered by the Russian explorer Bellingshausen in 1821, and extensive summer pack ice and its isolated location far from regular shipping lanes have restricted visits to the island.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
