Nishino-shima (Volcano Islands, Japan): (7 Aug) The Japan Coast Guard (JCG) released a new series of images of the volcano from a reconnaissance flight on July 17. Discolored water continues to be detected in the vicinity of the volcano, likely associated with the hydrothermal system beneath the edifice. In this system, hot water and steam interact with the surrounding rocks, dissolving minerals and leading to changes in water color, such as a yellow-to-green tint due to sulfur dioxide and hydrogen sulfide. Additionally, the imagery shows a sustained small crater pond on the crater floor and white steam emissions rising from fumaroles.
