To evaluate these signals as reliable seismic precursors and effective predictive tools, we studied the geochemical processes that caused these anomalies. Using chemical and isotope models, we show that increased concentrations of arsenic and vanadium, a slight increase in boron concentrations, and a concomitant lowering of the boron isotope ratio may be due to mineral desorption (e.g., from iron oxides and/or clays). We argue that a displacing effect on the trace elements sorbed on minerals was triggered by an excess of deep CO<jats:sub>2</jats:sub> in groundwater, which occurred prior to the main seismic event as a result of preseismic crustal dilation. Our observations confirm the pivotal role of CO<jats:sub>2</jats:sub> in the release of trace elements by alteration of solid phases and provide a new understanding of earthquake‐related water chemical anomalies.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380861291456735234","@type":"Researcher","foaf:name":[{"@value":"T.
