June 25, 2026—Kīlauea summit eruption reference map
This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. Most of the data for this map were collected during a Hawaiian Volcano Observatory helicopter overflight on June 9, 2026. As such, the provided statistics are reflective of the first forty-eight episodes of the eruption through June 1, 2026. A forty-ninth lava fountaining episode occurred on June 14; its lava flows could not be mapped during the post-episode overflight yesterday, June 24, due to poor weather.
