Bridgeman Island is a small 0.9 x 0.6 km remnant of a much larger volcanic edifice that is now largely submerged. It was constructed along the axis of the Bransfield Rift spreading center between the Shetland and Wedell tectonic plates. Bridgeman is located east of King George Island at the NE end of the Shetland Islands, north of the tip of Graham Land Peninsula. The 240-m-high island has a gently sloping top consisting of truncated lava flows. Steep cliffs surrounding the island expose older lavas and bedded pyroclastic rocks. The extensively eroded volcano does not display youthful volcanic features, although it has been characterized as a now inactive late Pleistocene-Holocene stratovolcano. Several reports of 19th-century fumarolic activity (Catalog of Active Volcanoes of the World) may instead refer to the much younger Penguin Island (González-Ferrán, 1972).
The Global Volcanism Program is not aware of any Holocene eruptions from Bridgeman Island. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Bridgeman Island page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

|Bridgeman Island, seen here from the SE, is a small 0.9 x 0.6 km remnant of a much larger volcanic edifice that is now mostly submerged. The base of the steeply cliffed island displays bedded pyroclastic rocks. An erosional surface cut into these rocks is filled by horizontal lava flows (left center). The extensively eroded volcano remnant does not display youthful volcanic features, and several reports of 19th-century fumarolic activity may instead refer to the much younger Penguin Island.
