Candlemas is an active stratovolcano. The north part of the volcano has
numerous scoria cones and lava flows. Glowing lava flows were reported in
1953-1954. The young lava flows on the north part of the island may have
been erupted since 1775 when the island was discovered. Steam emissions,
geysers, and hot pools have been reported several times this century.
Vindication Island, just southwest of Candlemas Island, is the eroded remnant of former stratovolcanoes. Vindication Island is mostly ice-free. Unlike most of the South Sandwich Islands, where basalt makes the volcanoes, the north part of Candlemas is made of andesite and dacite. There is no evidence for activity at this volcano in the last 10,000 years.
