Geological Summary

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).

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.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
