Isotopic compositions of water (δD and δ¹⁸O). () Cluster of hot mineral springs (Isotovsky, Koryaksky Narzan, Pinachevsky, total of 36 samples, 2010–2016) and Bystrinsky cold groundwater reservoir (7 samples from 2010–2016); (2) one cold spring at a foothill of Avachinsky Volcano (2200 masl) and Elisovo cold groundwater reservoir (7 samples, 2014–2016); (3) cluster of hot mineral springs (Chistinsky, Vodopadny, total of 4 samples, 2014–2016) and cold springs at a north foothill of Koryaksky Volcano (total of 7 samples, 2010–2016); (4) water phase from Western Kamchatka CH₄-water reservoirs (Kshuksky, Nizhne-Kvakchiksky, total of 12 samples, 2010–2016); (5) water condensate from Avachinsky and Koryaksky Volcano fumaroles (14 samples, 1997, 2010–2016); (6) Ketkinsky geothermal field line (5 samples, 2014); (7) Kamchatka representative sites of meteoric water samples (with elevations, masl) and meteoric line. Sampling was performed by A. Kiryukhin (1–7), T. Rychkova (6), Y. Taran (5), N. Malik (5), and P. Voronin (3). Analyses of samples were performed by P. O. Voronin and A. Y. Polyakov using an LGR IWA 45EP isotopic analyzer.
