Geological Summary

The solitary ice-covered shield volcano of Bouvet Island is located just off the Southwest Indian Ridge, east of the triple junction between the African, South American, and Antarctic plates. This basaltic-to-rhyolitic island, also referred to as Bouvetoya, was discovered by and later named for Captain Lozier-Bouvet during his 1739 search for the "great southern continent." About 95% of the uninhabited 10-km-wide island is covered by glaciers. The most prominent feature is the 3.5-km-wide Wilhelmplataet caldera, which is breached to the sea on the NW side. A late-stage rhyolitic lava dome forms the Cape Valdivia peninsula on the N flank. The latest dated eruption produced a lava flow at Cape Meteor on the eastern flank about 2000 years ago.

Photo Gallery


The uninhabited, ice-covered shield volcano of Bouvet Island is depicted from the SE in this November 26, 1898 water color painting. About 95% of the 10-km-wide island is glaciated, and sampling on this basaltic-to-rhyolitic volcano has been restricted to coastal cliffs. A caldera on the opposite (NW) side of the island is breached to the sea. Bouvet, also referred to as Bouvetoya, is located just off the Southwest Indian Ridge, east of the triple junction between the African, South American, and Antarctic plates.

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.
