Ongoing swarms of earthquakes and persistent volcanic tremors indicate active magmatic movement, fueling anticipation about Kīlauea’s next eruption.

After nearly 10 hours, Episode 40 of the Halemaʻumaʻu eruption comes to a sudden end.

While the mid-20th century episodic eruption and current ongoing eruption within the summit caldera of Kīlauea volcano on the Big Island share similarities, there also are several differences.

The scheduled operations including projects for invasive species control, aerial mapping of vegetation, seed collection and more; the park “regrets” any noise impact to residents and visitors.

Often spotted by onlookers in Hawaiʻi Volcanoes National Park, or even by YouTube livestream viewers, the long, ashy gray or brown, ropy cloud-like structures tend to appear near or downwind of active lava fountains.

On the one-year anniversary of Kīlauea’s rare episodic eruption, viewers watching the live feed at the summit were shocked to see two men walk in front of the camera that is in a restricted area.

The most recent eruptive event at the summit of the Big Island lasted about 8.1 hours less than the first episode that started the eruption a year ago on Dec. 23, 2024, but produced higher fountains and more lava output.

The rare ongoing eruption within Halema’uma’u Crater inside the summit caldera of the Big Island volcano began Dec. 23, 2024, with Episode 39 expected any day now.

Hawaiʻi health officials have issued a warning about deteriorating air quality due to lingering volcanic gases from Kīlauea, urging residents and visitors to limit exposure to the vog.

Hawaiʻi Volcanoes National Park rangers want visitors to have a safe and memorable adventure this holiday season. Safety is their top priority, but it is your responsibility.

Scientists at the Hawaiian Volcano Observatory, in collaboration with the U.S. Geological Survey, have installed a new livestream monitoring camera at Kīlauea on the Big Island.

Join Hawaiian Volcano Observatory staff and its partners Hawaiʻi Volcanoes National Park, University of Hawaiʻi at Hilo and Hawaiʻi County Civil Defense in January 2026 for a series of programs around the island that will discuss eruptions and earthquakes, how Hawaiian Volcano Observatory scientists monitor them and the hazards associated with them.

At 10 a.m., livestream cameras from the U.S. Geological Survey showed smoke billowing out of the Halema‘uma‘u Crater.

The V3cam on the south rim of Kīlauea was buried under 50 feet of tephra, abruptly ending its livestream.

The latest episode in the series that began nearly a year ago on Dec. 23, 2024, ended abruptly at 8:52 p.m. Saturday (Dec. 6), after a little more than 12 hours, when the south vent — which exploded earlier during the day and featured sustained fountaining as high as 1,200 feet at one point — ceased activity.

The 1975 Kalapana earthquake has ultimately changed the understanding of Kīlauea’s south flank, and the hazards associated with its movement.

Episode 37 of the ongoing Halemaʻumaʻu eruption began on Tuesday at 2:30 p.m., and 9.2 hours it abruptly ended.

The largest Hawaiʻi earthquake of the 20th century and so far in the 21st century happened 50 years ago this month; shaking as well as ground subsidence and a local tsunami contributed to a catastrophic sequence of events Nov. 29, 1975.

Kīlauea’s paused summit eruption shows signs of reawakening, with glowing vents, and tremor spikes continue. Hawai’i Volcanoes National Park is advising the public to remain cautious of volcanic hazards such as vog and Pele’s hair.

Fountaining episodes during the past month and a half broke several records for this eruption, including the highest lava fountains, the most volume of lava erupted and the highest rate of lava effusion for this event, which has now lasted more than 10 months.
