Summary

This data release contains selected results of whole-rock and glass analyses of lava samples collected during the 2018 eruption of Kilauea’s lower East Rift Zone (LERZ). Included are sampling-site information, eruptive vent/fissure, and sampling descriptions. During the 2018 LERZ eruption, the chemical analysis of lava samples was performed within hours of collection using an energy-dispersive X-ray fluorescence (ED-XRF) pressed-pellet methodology. The accuracy of this method was evaluated by analyzing a subset of samples using the more widely accepted wavelength dispersive X-ray fluorescence (WD-XRF) fused-bead methodology. WD-XRF analyses were performed both during and after the eruption at the Hamilton Analytical Lab, Hamilton College, [...]

Purpose

The samples were collected and analyzed as part of the eruption response led by the USGS Hawaiian Volcano Observatory (HVO) and the University of Hawaii at Hilo Geology Department (UHH) during the 2018 LERZ eruption of Kilauea volcano. The objective of the analysis was to characterize the pre-eruptive chemistry of the magma and track changes over the course of the eruption in near-real time.
