Kilauea: Hawaii volcano erupts again spewing toxic gases and volcanic smog
Hawaii’s Kīlauea volcano has entered its fifth eruptive episode since late December 2024, resuming activity at 2:57 p.m. HST (7:57 p.m. ET) on January 22, 2025.
Fountains of lava between 16 and 33 feet high have been observed, accompanied by a short lava flow from the volcano’s north vent.
The U.S. Geological Survey (USGS) reported seismic tremor increasing as the eruption began, with ongoing inflation beneath Halemaʻumaʻu crater indicating continued activity.
“Once sufficient pressure builds, it can push magma up to the surface to start another eruptive episode,” Katie Mulliken, a geologist at the Hawaiian Volcano Observatory (HVO), told Newsweek.
“Episodes are marked by the onset of lava fountains and rapid deflation of the source magma chamber.”

Why This Matters
Kīlauea is one of the most active volcanoes in the world, having erupted dozens of times since 1952.
While the current eruption is by no means the largest or longest at the volcano, significant hazards persist for residents and visitors.
How Dangerous is the Hawaii Eruption?
Kīlauea’s current eruption activity remains confined within the Halemaʻumaʻu crater and Kaluapele, located in Hawai’i Volcanoes National Park. While the activity is contained within a closed area of the National Park, the HVO has warned of several hazards.
Volcanic gas emissions of water vapor, carbon dioxide and sulfur dioxide are the “primary concern,” as they can be blown over large distances. Sulfur dioxide, in particular, reacts with the atmosphere to form a visible haze known as volcanic smog, or “vog”.
Anyone’s health can be impacted when inhaling vog, but sensitive groups such as people with respiratory conditions, older adults, children and pregnant women should exercise extra caution.
Current air quality data from the Hawaii State Department of Health shows conditions have not deteriorated as of yet, with all monitoring stations at “good” levels on the island.
Pele’s hair—strands of volcanic glass produced by lava fountains and carried by the wind—is another hazard associated with eruptions at Kīlauea.
“As lava is ejected through the air, lava particles can be stretched apart, and the material in between can become very thin and form the glassy strands,” Mulliken said.
“It can sometimes cluster and tangle together on the ground, giving it the appearance of a tumbleweed.”
Mulliken confirmed that during the fourth eruptive episode, which ended on January 18, Pele’s hair reached residential communities within several miles of the summit.
She added, “Hazards associated with Pele’s hair are similar to those associated with volcanic ash. Both are abrasive particles with sharp edges that can irritate eyes, respiratory systems and skin.
“Most Pele’s hair is too large to be inhaled, but people with existing respiratory diseases, like asthma, might find that their symptoms are worse when they are exposed to airborne volcanic particles.”
Anyone in the area is advised to limit exposure to volcanic gases and Pele’s hair where possible.
What Happens Next
Live webcams positioned at Kīlauea’s summit reveal the eruption was still ongoing as of 2:14 a.m. HST (7:14 a.m. ET).
HVO is continuing to monitor the situation and is expected to release another update later this morning.
Each eruptive episode at Kīlauea has lasted between 14 hours and 8 days, separated by a pause of 1 to 12 days. Its unclear how long this current episode will last.

2026 Sony Open field is announced. See who’s playing in Hawaii
The Sony Open in Hawaii has the honors of being the kickoff event to the 2026 PGA Tour season after the cancellation of The Sentry at Kapalua this season.
Instead of Maui, the Tour debuts in Honolulu on the island of Oahu, Jan. 15-18, at the Seth Raynor-designed Waialae Country Club, where Nick Taylor prevailed in a playoff over Nico Echavarria last year.
Among the changes this season is the field size, which was reduced from 144 to 120, and, there is no longer is a Monday qualifier offering four spots. Will that help with pace of play? Stay tuned.
The field includes the following notables in addition to Taylor and Echavarria: Daniel Berger, Keegan Bradley, Michael Brennan, Corey Conners, Tony Finau, Chris Gotterup, Brian Harman, Russell Henley, Billy Horschel, Robert MacIntyre, Collin Morikawa, Adam Scott, Jordan Spieth, Sahith Theegala, Gary Woodland and 62-year-old Vijay Singh.
Here’s the full field for the Sony Open, which will be live on Golf Channel all four days as well as NBC with early-round coverage on Saturday and Sunday.
This year’s Sony purse is $9.1 million and the winner also will receive 500 FedEx Cup points.
