May 29, 2025 — Kīlauea summit fieldwork after episode 23
Detailed Description
During the pause after episode 23 of the ongoing Kīlauea summit eruption, a USGS Hawaiian Volcano Observatory scientist collects data on the tephra deposits. Buckets are used to collect tephra, and emptied between episodes, to ensure that samples from each episode are isolated to track geochemical changes and determine the amount of tephra that fell at each site. The stake also helps scientists measure the thickness of tephra fall in that area. USGS photo taken by L. DeSmither on May 29, 2025.
