September 17, 2023 — Kīlauea summit sampling
Detailed Description
USGS Hawaiian Volcano Observatory geologists collected tephra samples erupted from Kīlauea summit on September 10th, 2023. The samples were collected from the rim of Halema‘uma‘u crater and range in size up to 1 inch (2.54 cm). This tephra was visibly less rounded than the existing tephra along the rim from the June 2023 eruption. Geochemical analysis of this tephra will share information related to the plumbing system and conditions prior to eruption. Photo taken by J. Schmith.
