Damby, D.E., Peek, S., Lerner, A.H., and Elias, T., 2018, Volcanic ash leachate chemistry from increased 2018 activity of Kīlauea Volcano, Hawaii: U.S. Geological Survey data release,


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 and May 28. The samples [...]

​This data release includes volcanic ash leachate, catchment and rainwater chemistry. These data were obtained to aid local health, environmental, and agricultural support agencies in their evaluation of potential hazards posed by the increase in volcanic ashfall from from the 2018 activity at Kīlauea volcano, Hawaii. These data are preliminary and eruption monitoring is ongoing. The information contained in this data release may be updated as more samples and information become available.
