June 26, 2025 — Kīlauea summit eruption lava thickness through episode 24

This map shows thickness values for lava flows within Halema‘uma‘u crater from the Kīlauea summit eruption that began on December 23, 2024. These values were calculated by topographic differencing between a digital elevation model collected on June 10, 2025—after eruptive episode 24—and one from before the eruption began. The maximum thickness is within the spatter cone at the north vent, standing 103 m (338 ft) above the pre-eruption surface. 

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, following each of the five summit eruptions from 2020–2023, and for this eruption following the end of episode 24. Also shown is the maximum depth of the 2019–2020 Halema‘uma‘u water lake. Previous versions of this profile view indicated the final fill depth of the 2023 eruptions as 1348 ft (411 m) above sea level; however, the volume-averaged surface elevation for these eruptions has been recalculated using a method more consistent with the other eruptions, yielding a new value of 1312 ft (400 m).
