Kilauea Erupts with Record-Breaking Lava Fountains

Why this matters: The eruption poses potential hazards from elevated gas levels and tephra, especially for those with respiratory conditions. The event highlights the dynamic nature of Kilauea and the importance of monitoring volcanic activity.

Kilauea’s recent eruption showcases its ongoing activity within Halemaumau crater. The eruption began on December 23, 2024, and this episode 35 marks a significant event with record-breaking lava fountains. The U.S. Geological Survey (USGS) is closely monitoring the eruption, providing live streams and updates.

The eruption has seen lava fountains spewing from both the north and south vents within the crater. The south vent fountains reached nearly 1,500 feet, while the north vent fountains measured around 1,100 feet. This level of activity has caused tephra (fine glass particles) to fall on areas southwest of the vents, including Highway 11. Elevated gas levels are also a concern, particularly for individuals with respiratory sensitivities.

Most episodes of lava fountaining have lasted a day or less, separated by pauses in eruptive activity. The current episode’s rapid tilt drop and high output suggest it may also be brief. Winds are carrying volcanic gas emissions and material south of Kilauea summit, potentially impacting areas along the southern and southwestern parts of Mauna Loa.

Actionable Takeaways:

Tephra consists of fine glass particles that can irritate the skin and eyes.

The Kilauea alert level remains at "watch," and the aviation color code is orange.

The eruption is confined to Halemaumau crater in Hawaii Volcanoes National Park.
