Refractive index measurements of volcanic glass shards with known hydration characteristics enable the discrimination of pumice samples from multiple historic eruption events of a single volcano. We analyzed mineral compositions, undertook a morphological clas-sification of volcanic glass shards, and measured the refractive index of glass shards and orthopyroxene from products of the Bunmei, An-ei, and Taisho eruptions of Sakurajima volcano. The refractive indi-ces of hydrated and non-hydrated parts within each individual glass shard were measured separately. Concentrations of 58 elements in the glass shards were determined using a femtosecond laser abla-tion–inductively coupled plasma–mass spectrometry technique, to compare elemental concentrations of the sampled glass shards. The analyses successfully discriminated the Bunmei, An-ei, and Taisho eruption products. Pumice layers in core samples obtained from the southern part of the Miyazaki Plain were identified as the Sakurajima-Bunmei tephra, based on the analyses described above and radiocarbon age data for coaly materials in the pumice layers. The distribution of the pumice layer suggests that the Sakurajima-Bunmei tephra reached the southern part of the Miyazaki Plain as a pumice fall deposit.
