In early May 2018, activity at Kīlauea volcano, Hawaii, increased, with heightened ash production from the summit commencing on May 17. Volcanic ash can scavenge volatile components from volcanic plumes, resulting in the deposition of potentially harmful elements during ash fallout. Leaching of these species (e.g., by rainfall or in water catchment systems) can have implications for agriculture, water resources and human health. The U.S. Geological Survey (USGS) is sampling volcanic ash and utilizing ash leachate analyses as part of the assessment of hazards from the ongoing eruption of Kīlauea Volcano. We acquired 30 ash samples erupted from the summit of Kīlauea Volcano and collected downwind between May 10...

This release includes data collected during campaign GPS surveys at Kīlauea and Mauna Loa Volcanoes on the Island of Hawaiʻi in 2021. It includes data from a total of 63 sites occupied from January 1 to December 31, 2021. For each site, we include its measured raw data in daily files, Receiver INdependent EXchange (RINEX) files for each day, field log sheet(s), and associated metadata information. We also include a few days of data at the end of 2020 at 3 longer-term campaign sites at Kīlauea’s summit. These sites (109Y, NDDB, OVRL) were deployed in late December 2020 in response to the December 20, 2020, Kīlauea summit eruption. The authors thank USGS Hawaiian Volcano Observatory staff, volunteers, and collaborators...

Data Description Campaign microgravity surveys have been conducted at Kīlauea, Hawai‘i (USA), since 1975 (Dzurisin and others, 1980) and, when combined with deformation measurements, enable insights into mass change within the volcano (Jachens and Eaton, 1980; Johnson, 1992; Kauahikaua and Miklius, 2003; Johnson and others, 2010; Bagnardi and others, 2014; Poland and others 2019). For example, microgravity surveys between 1975-2008 measured residual gravity increases of up to 0.450 mGal across the volcano’s summit and have been interpreted as filling of void space by magma (Johnson and others, 2010). In March 2008 a new long-lived eruption began within Kīlauea’s Halema‘uma‘u crater (Wilson and others, 2008) which...
