Collecting tephra at Kīlauea summit - September 11, 2023
USGS Hawaiian Volcano Observatory geologists collected samples that erupted on September 10th, 2023, during the ongoing eruption within Kīlauea summit caldera. The samples were collected from within strategically placed buckets along the rim of the crater. The samples will be analyzed later for information about the lava erupted during the eruption.
