Fukujin is an active submarine volcano of the Mariana Volcanic Arc that last erupted in 1974. The summit is located about beneath the ocean surface,[1] although in 1977, it was measured at and a shoal depth of was obtained in 1980. No minimum depth has been recorded as the presumably shallow depth poses a risk to ships. It measures across. Volcanic activity in the 1970s is believed to be centered along a southwestern flank vent at depth.[2]
