What's New
One of the world's most active volcanoes, Kilauea, began erupting Monday at approximately 2 a.m. HST on Hawaii's Big Island, prompting health warnings as volcanic smog threatened downwind communities.
The U.S. Geological Survey (USGS) elevated its volcano alert level from "Advisory" to "Warning" and aviation color code from yellow to red.
By 2:30 a.m., webcam imagery captured lava fountains emerging through fissures in Halemaʻumaʻu within Kaluapele (the summit caldera).
Newsweek has contacted the Hawaii Volcanoes National Park via online form on Monday afternoon for comment.
Why It Matters
Kilauea stands as one of Earth's most consistently active volcanoes, with regular eruptions documented since 1983.
This event marks its latest eruption, following previous volcanic activity in June and September 2024. While currently confined to Hawaii Volcanoes National Park's restricted area, the eruption raises significant health concerns through volcanic gas emissions.
A 2018 eruption demonstrated Kilauea's destructive potential when it destroyed more than 700 homes in the Puna District between May and August, while thousands of earthquakes dramatically altered the summit area.
What To Know
The eruption is occurring within the Halemaʻumaʻu crater in an area closed to the public since late 2007. Primary hazards include high levels of volcanic gases—predominantly water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2). When SO2 is released, it reacts in the atmosphere to create volcanic smog (VOG) downwind, according to the USGS.
Additional hazards include lightweight volcanic glass fragments that can fall downwind of the fissure vents, potentially causing skin and eye irritation within a few hundred meters of the vents.
Strong winds may carry lighter particles greater distances. The area around Halemaʻumaʻu crater remains hazardous due to crater wall instability, ground cracking, and rockfalls that can intensify during earthquakes.

USGS Hawaiian Volcano Observatory (Official Notice) reads: "The opening phases of eruptions are dynamic. Webcam imagery shows a line of fissures erupting lava fountains feeding lava flows at the base of Halemaʻumaʻu within Kaluapele."
Hawaii Volcanoes National Park in a statement said: "Hazardous volcanic gases are billowing out the crater and present a danger to everyone, especially people with heart or respiratory problems, infants, young children and pregnant women."
What Happens Next
The Hawaii Volcano Observatory continues monitoring gas emissions and seismic activity, working closely with park officials and civil defense to implement additional safety measures as needed.
Residents in areas affected by volcanic smog should stay informed about air quality conditions and follow official guidance regarding protective measures.
