BackgroundUninhabited 5 x 10 km wide Prince Edward Island lies opposite Marion Island at the northern end of a submarine plateau on the Antarctic Plate immediately south of the SW Indian Ocean Ridge. The low-angle Prince Edward Island is a remnant of a large shield volcano formerly centered off the current NW shore of the island. Pleistocene and Holocene scoria cones and tuff cones are located throughout the unglaciated 672-m-high island, which was active contemporaneously with nearby Marion Island. Fifteen of the scoria cones and four tuff cones on the coastal plain were active during the Holocene.
