Volcano Islands, Japan, 27.27°N / 140.88°E
Current status: restless (2 out of 5)
Nishinoshima volcano (西之島, Nishi-no-shima meaning literally: Western Island, also: Rosario Island) is the tiny submerged part of a caldera in the northern Volcano Islands of Japan. The small 700 m wide island was significantly enlarged during the last eruption in 1974, which joined several new islands that formed then.
Water discoloration due to possible minor eruptions and / or shallow submarine hydrothermal activity in the area is a frequent sight.
The mostly submerged volcano is a massive seamount with prominent flank cones on the south, west and NE flanks. The southern cone rises to a depth of 214 m below the sea surface, 9 km SSE of Nishinoshima.
