Discolored water was seen 14 October and 10, 24, and 26 January. Five greenish circular spots were observed on 10 January and eruptions occurred about once every 2 minutes on 24 January.
Geologic Background. One of the larger of the submarine volcanoes of the Marianas arc, Fukujin seamount has risen on occasion to just beneath the sea surface. Intermittent periods of water discoloration have been observed since the mid-20th century, and eruptions producing floating pumice were noted on several occasions.
