April 9, 2025—Kīlauea summit eruption reference map

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. As of this posting on April 9, the eruption has had seventeen episodes, with the most recent concluding earlier this morning. However, most of the map data included here were collected during a Hawaiian Volcano Observatory helicopter overflight on April 2, immediately following episode 16; for this reason, the provided statistics only reflect the first sixteen episodes of the eruption. Additionally, the collected data were insufficient to calculate the total lava volume for the eruption at that time.
