KILAUEA (VNUM #332010)

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Activity Summary:
The ongoing Halema‘uma‘u eruption is currently paused. Episode 24 ended on June 5. Summit inflation has resumed, along with persistent, low level seismic tremor. Additional time is needed to accumulate tiltmeter data before a forecast window can be made for episode 25. However, given that the deflationary tilt during episodes 24 and 23 was similar, we expect a roughly similar pause following episode 24. The pause between episodes 23 and 24 was 10 days.
Data analysis has confirmed that lava fountains from episode 24 reached heights of approximately 1,200 feet (365 meters), which were slightly higher than episode 23, and a new record for the current eruption.
Fountaining episodes have occurred approximately once per week since the start of the eruption on December 23, 2024. All eruptive activity remains within Hawaiʻi Volcanoes National Park. No significant activity has been noted along Kīlauea’s East Rift Zone or Southwest Rift Zone. Current hazards include volcanic gas emissions and windblown volcanic glass (Pele’s hair) and tephra that have impacted Hawaiʻi Volcanoes National Park and nearby communities.
Summit Observations:
Episode 24 ended at approximately 4:28 a.m. on June 4. Lava flows from this episode on the floor of Halemaʻumaʻu within the southern part of Kaluapele (Kīlauea caldera) may continue to exhibit slow movement or incandescence as the cool and solidify over the coming days.
Data analysis has confirmed that lava fountains from episode 24 reached heights of approximately 1,200 feet (365 meters), which were slightly higher than episode 23, and a new record for the current eruption.
The average sulfur dioxide (SO2) emission rate during inter-episode pauses is typically around 1,200 tonnes per day (t/d).
Strands of volcanic glass known as Pele’s hair are present throughout the summit area of Hawaiʻi Volcanoes National Park and surrounding communities and can be remobilized by wind.

The B2, KW, and F1 summit webcams are currently offline due to eruption impacts. Other HVO summit webcams are functioning and online.
Rift Zone Observations:
Rates of seismicity and ground deformation remain very low in the East Rift Zone and Southwest Rift Zone with no significant earthquake activity in the past 24 hours. Sulfur dioxide (SO2) emissions from the East Rift Zone remain below the detection limit.
