July 21, 2023—Reference map of recent Kīlauea summit eruption

This reference map depicts the Kīlauea summit region following the most recent eruption in June 2023. The provided statistics for that eruption were measured during a Hawaiian Volcano Observatory helicopter overflight just days after the June 19 eruptive pause. Also included here are west-to-east profiles across the summit caldera, depicting topographic changes since 2018. Profiles are provided for the periods before the 2018 caldera collapse, shortly after the 2018 collapse, and following each of the four summit eruptions since 2020. Also shown is the maximum depth of the 2019–20 Halemaʻumaʻu water lake.
