Based on hydrogeochemical changes following an earthquake of magnitude (M<jats:sub>w</jats:sub>) 5.8 on 16 September 2002, we constrained the timescales of post‐seismic fault sealing and water–rock interaction. We interpret that the earthquake ruptured a hydrological barrier, permitting a rapid influx of chemically and isotopically distinct Ice Age meteoric water from a second aquifer. During the two subsequent years, we monitored a chemical and isotopic recovery towards pre‐earthquake aquifer compositions, which we interpret to have been mainly facilitated by fault‐sealing processes. This recovery was interrupted in November 2004 by a second rupturing event, which was probably induced by two minor earthquakes and which reopened the pathway to the second aquifer. We conclude that the timescale of fault sealing was approximately 2 years and that the approach to isotopic equilibrium (from global meteoric water line) was approximately 18% after >10<jats:sup>4</jats:sup> years.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699993828646016","@type":"Researcher","foaf:name":[{"@value":"L.
