Wednesday, Jan 29, 2020
A new eruption has been occurring at the volcano since mid Dec last year. The eruption seems to be mainly effusive, as satellite imagery shows lava flows traveling from the summit vent towards the NE where they reached (or maybe are still entering) the shore. ... [details]

HeureMag. / DepthDistanceLocation
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.
