Ash from an explosive event at Halema‘uma‘u on May 15, 2018, was blown by trade winds to the southwest, where it fell from the plume and blanketed the Ka‘ū Desert landscape. Samples of this ash were collected for ash leachate analyses as part of the assessment of hazards from Kīlauea Volcano's eruption.
