A study on the water environment of around Mt.Ontake after eruption (140927) (8)

Abstract

A steam explosion eruption in Ontaki that occurred in 2014 released a volcanic ejecta, and it was expected that this ejecta will affect the water quality of the surrounding river and mountain area lake group. So we tried to keep track of the change of water quality due to the eruption of this year for Ontakeyama, to continue the survey and follow the progress with the passage of time.
