Photo & Video Chronology — June 6, 2025 — Kīlauea Episode 24

By Hawaiian Volcano Observatory June 9, 2025

The ongoing Kīlauea summit eruption that began on December 23, 2024, is currently paused following the high fountaining of episode 24 for 7.5 hours on June 4-5, 2025.

This timelapse video shows the lava fountaining during episode 24 of the ongoing summit eruption of Kīlauea. The main fountain, at the north vent (right), grows quickly and soon surpasses the top of the camera image, reaching over 300 meters (1000 ft) high. Much of the lava from this vent was deposited to the southwest, over the rim and nearby Crater Rim Drive (an area of Hawai‘i Volcanoes National Park that remains closed to the public).

Black and white photograph showing volcanic particles falling near a webcam — The webcam monitoring the Southwest Rift Zone of Kīlauea is downwind of the vents active during the ongoing eruption at the summit, and it was in the fallout zone of tephra coming from the episode 24 lava fountaining. This image shows a barrage of clasts falling around the camera, with the camera view knocked out of alignment.

This map shows lava flow and tephra accumulation at Kīlauea volcano associated with episode 23 of the ongoing eruption in Halemaʻumaʻu that started on December 23, 2024. The image covers the timespan from May 22–30, 2025, using data recorded by the Italian Space Agency's (ASI) COSMO-SkyMed Second Generation satellite constellation. This map combines cross-polarized radar amplitude images taken on two different dates, along with interferometric coherence from the time between those dates. This approach enables the detection of volcanic mass flows (such as lava flows) and other tephra-fall deposits regardless of surface or weather conditions. In the map, unchanged barren areas are represented in blue/purple, vegetated areas appear in yellow/light green, and new deposits over barren land are shown in either dark or bright green. The bright green areas show the extent of lava flows in Halemaʻumaʻu and tephra that was deposited southwest of Halemaʻumaʻu during episode 23, when lava fountains were active for 6 hours on May 25. Tephra are volcanic fragments, such as Pele's Hair and scoria, that travel through the air before falling on the ground. Lava fountains during episode 23 reached up to 1150 ft (350 meters) and tephra was deposited over 2 miles (3.5 kilometers) from the vents in a south-southwest direction.

Tephra are volcanic fragments, such as Pele's Hair and scoria, that travel through the air before falling on the ground. Lava fountains during episode 24 reached up to 1200 ft (365 meters) and tephra was deposited nearly 2 miles (3 kilometers) from the vents. The white-ish streak to the south-southwest is the very reflective surface of the tephra deposits from episode 23.

Color map showing eruption location — This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. As of this posting on June 6, the eruption continues episodically. Most of the map data included here were collected during a USGS Hawaiian Volcano Observatory helicopter overflight on May 28, between episodes 23 and 24; for this reason, the provided statistics only reflect the first twenty-three episodes of the eruption. Additionally, the collected data were insufficient to calculate the total lava volume for the eruption at that time.
