Heat, water and chloride budgets were evaluated with a box model. Until 1989, heat and chloride inputs into the lake were 3∼10 MW and 1∼3.5 tons/day, respectively; but these increased to 19–25 MW and 4–12 tons/day by 1990. The strong correlation between the Cl<sup>–</sup> concentration and lake water pH suggests input of a HCl solution or HCl vapor as the cause of the Cl<sup>–</sup> change. These changes coupled with the high level of seismicity observed around the volcano in 1990 seem to be consistent with the formation of fractures in the surrounding area of a cooling magma."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420564276164690688","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"60203915"},{"@type":"NRID","@value":"1000060203915"},{"@type":"NRID","@value":"9000000786782"},{"@type":"NRID","@value":"9000003235168"},{"@type":"NRID","@value":"9000415352757"},{"@type":"NRID","@value":"9000411392415"},{"@type":"NRID","@value":"9000413247182"},{"@type":"NRID","@value":"9000402908809"},{"@type":"NRID","@value":"9000014234893"},{"@type":"NRID","@value":"9000254261987"},{"@type":"NRID","@value":"9000254740502"},{"@type":"NRID","@value":"9000257916774"},{"@type":"NRID","@value":"9000414744535"},{"@type":"NRID","@value":"9000415352942"},{"@type":"NRID","@value":"9000002108647"},{"@type":"NRID","@value":"9000404530304"},{"@type":"NRID","@value":"9000254146547"},{"@type":"NRID","@value":"9000415089219"},{"@type":"NRID","@value":"9000001668133"},{"@type":"NRID","@value":"9000254579113"},{"@type":"NRID","@value":"9000324639881"},{"@type":"NRID","@value":"9000257916779"},{"@type":"NRID","@value":"9000259836345"},{"@type":"NRID","@value":"9000262362880"},{"@type":"NRID","@value":"9000411392434"},{"@type":"NRID","@value":"9000408783368"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0059130"}],"foaf:name":[{"@language":"en","@value":"Ohba Takeshi"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Kusatsu-Shirane Volcano Observatory, Tokyo Institute of Technology"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282679527180800","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254579114"}],"foaf:name":[{"@language":"en","@value":"Hirabayashi Jun-ichi"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Kusatsu-Shirane Volcano Observatory, Tokyo Institute of Technology"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282679527180802","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254579115"}],"foaf:name":[{"@language":"en","@value":"Nogami Kenji"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Kusatsu-Shirane Volcano Observatory, Tokyo Institute of Technology"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00167002"},{"@type":"LISSN","@value":"00167002"},{"@type":"EISSN","@value":"18805973"}],"prism:publicationName":[{"@language":"en","@value":"GEOCHEMICAL JOURNAL"},{"@language":"ja","@value":"ＧＥＯＣＨＥＭＩＣＡＬ　ＪＯＵＲＮＡＬ"},{"@language":"en","@value":"Geochem.
