From Wikipedia

Fukujin is an active submarine volcano of the Mariana Volcanic Arc that last erupted in 1974. The summit is located about 217 m (712 ft) beneath the ocean surface, although in 1977, it was measured at 70 m (230 ft) and a shoal depth of 3 m (9.8 ft) was obtained in 1980. No minimum depth has been recorded as the presumably shallow depth poses a risk to ships. It measures 40 km (25 mi) across. Volcanic activity in the 1970s is believed to be centered along a southwestern flank vent at 1,200 m (3,900 ft) depth.
