This data release contains information about the lava samples that were collected during two volcanic eruptions of Kīlauea Volcano, Island of Hawai‘i. The first eruption occurred from 1983 to 2018 at Pu‘u‘ō‘ō and the second occurred contemporaneously from 2008 to 2018 at the summit lava lake. The data release provides a comprehensive list of lava samples that are currently stored in the physical sample archive of the Hawaiian Volcano Observatory (HVO). The information in the data release includes details about the sampling sites and how the samples were collected. Most of the samples were collected to study the pre-eruptive chemistry and petrology of the magma that fed the eruption and to track its changes over time. Therefore, most samples are water or air quenched-lavas that were collected as close to the eruptive vent as possible. It is important to note that this data release does not include any analytical results of chemical analyses. It only provides metadata about the sampling events and the samples themselves.

A limited suite of samples for the 2020–2023 Kīlauea eruptions within Kaluapele (the summit caldera) were collected by the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) field teams from within a publicly closed area of Hawai‘i Volcanoes National Park in cooperation with the National Park Service. This data release presents sample metadata, whole rock ED-XRF, whole rock WD-XRF, whole rock LA-ICP-MS, glass EPMA, glass LA-ICP-MS, leachate, and isotope data for these samples.
