Event overview

Kilauea on Hawaii’s Big Island produced dramatic lava fountains that reached roughly 1,000 feet during the latest episode, which marked the eruption’s 43rd since it began in December 2024; the event prompted temporary closures at Hawaii Volcanoes National Park and part of an important highway because of falling glassy volcanic fragments and ash.

Scale and history

The eruption has produced episodes of varying scale and duration: some episodes have lasted hours while others have gone on for days.

Past activity has included exceptionally large lava output — one episode released just under 11 million cubic yards of lava, a volume CBS compared to filling an Olympic‑sized swimming pool every 5½ seconds.

Kilauea is also described by officials as one of the world’s most active volcanoes.

Local impacts

Hawaii County opened a shelter at a district gymnasium for residents and tourists affected by road closures or falling tephra; one report said the shelter had no occupants soon after it opened.

One outlet also reported flight cancellations related to the episode.

Hazards and warnings

Authorities and forecasters warned about airborne volcanic fragments (tephra) and ash, with the National Weather Service issuing an ashfall warning and projecting accumulations over parts of the park.

Officials cautioned that tephra can irritate eyes, skin and the respiratory system and can clog common water‑catchment systems on the island.

The falling glassy fragments — described in some accounts as including ash — were the principal reason for the park and road closures.

Ongoing uncertainty

The situation remained fluid: a livestream showed two fountains of bright‑red lava and smoke while reports emphasized that it was unclear how long the fountaining would last.
