Falcon Island is seen from the SE showing the active crater through the SE breach; a steam column is dispersed to the NW by dominant SE Trade Winds. The ephemeral Falcon Island in the central part of the Tonga Islands was named after the British vessel H.M.S. Falcon, which reported a shoal in 1865. Falcon Island has been the site of island-forming eruptions on at least two occasions since the 19th century. By 1949 the island had eroded beneath sea level, but the summit of the volcano remains at shallow depths.
