This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. The data for this map were collected during a Hawaiian Volcano Observatory helicopter overflight on January 2, 2026; as such, the provided statistics are reflective of the first thirty-nine episodes of the eruption through December 24, 2025.

This map shows thickness values for lava flows within Halema‘uma‘u crater from the Kīlauea summit eruption that began on December 23, 2024.

This 1:5,000,000-scale geologic map of the Guinevere Planitia quadrangle divides the region into 15 geologic material units, defined using Magellan synthetic aperture radar (12.6-centimeter-wavelength radar system; 75 meters per pixel) datasets and including upland terrain units (2.4 percent of the surface area), plains materials units (59 percent), flow materials associated with named...

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. As of this posting on December 11, 2025, the eruption has had thirty-eight episodes, with the most recent occurring on December 6.

These three thermal maps were made from oblique thermal images collected during helicopter overflights of Kīlauea summit. The collection dates bracket the last two episodes of lava fountaining - episode 37 was on November 25 and episode 38 was on December 6.

This map shows lava flow and tephra accumulation at the summit of Kīlauea volcano associated with episode 38 of the ongoing eruption in Halemaʻumaʻu that started on December 23, 2024
