Summary

Kilauea volcano (Hawaii, USA) is a shield volcano that exhibits both effusive and explosive eruptive activity. Although Kilauea has been predominantly built through effusive eruptions, explosive eruptions have occurred repeatedly at both Kilauea's summit and in the volcano's lower East Rift Zone (Moore, 1992; Swanson et al., 2014). This dataset presents geochemical analyses of samples from Kapoho Crater and Puulena Crater, which formed during powerful explosive eruptions in Kilauea's lower East Rift Zone. The eruption ages of Kapoho Crater and Puulena Crater are estimated to be ~1400-1700 CE and 1250-1600 CE, respectively, based on correlations with dated regional lava flows (Moore and Trusdell, 1991). The samples in this dataset [...]

Purpose

Data were collected to understand the magmatic compositions of notable explosive eruptions in Kīlauea volcano's lower East Rift Zone and assess volatile contents and magma storage depths of these units. These geochemistry data compliment a broader study of these units, including morphology, geologic setting, and ash componentry, presented in Hazlett et al., 2024. Data were used for research purposes and to inform hazard analysis.
