Hawaii — Kīlauea Remains on Orange Alert as USGS Watches for Fountains

Kīlauea volcano on Hawaii's Big Island remains under an orange alert, a status the U.S. Geological Survey uses to signal elevated unrest short of an active eruption, according to Fox News. The alert has triggered trail closures inside Hawaiʻi Volcanoes National Park, a draw for visitors who come to view the summit caldera and its lava lake from marked overlooks.

What alert level is Kīlauea under right now?

The orange designation sits in the middle of the USGS four-color volcano alert scale, below red, which is reserved for eruptions already underway or imminent. Fox News reports USGS scientists are actively monitoring the summit for signs that could precede a new round of lava fountaining, rather than declaring an eruption has started.

Which trails are closed at Hawaiʻi Volcanoes National Park?

Fox News reports the volcano's renewed activity has forced immediate trail closures at the park, a step officials take when ground deformation or gas emissions near viewing areas pose a risk to hikers. The report does not specify which individual trails are shut or for how long, and the park has not published a reopening timeline in the material reviewed for this story.

Why are two vents spattering again?

According to the reporting, USGS observers have recorded renewed spattering — brief ejections of lava and gas — at two vents within the summit crater. Spattering of this kind has preceded earlier lava fountain episodes at Kīlauea's summit, which is why USGS is treating the activity as a precursor worth close monitoring rather than routine background noise.

What would a new lava fountain episode involve?

Fox News reports USGS is watching for the possibility of another episode of lava fountains at the summit, a pattern in which molten rock is thrown skyward from a vent for a period before subsiding. Past episodes at Kīlauea have drawn visitors to safe overlook areas when conditions allow, but each new episode also carries the gas and ejecta hazards that justify closing nearby trails first.

What should travelers heading to the park watch for?

• Check the park's official alert status before arriving, since closures tied to vent activity can change quickly.
• Expect overlook and viewing-area access to shift as USGS updates its monitoring of the two spattering vents.
• Treat orange-alert status as active unrest, not a confirmed eruption, when planning a visit.
• Follow posted trail closures inside Hawaiʻi Volcanoes National Park rather than relying on past visit experience.

No casualty, evacuation order, or fixed reopening date appears in the reporting reviewed for this story. HTT News will update this explainer as USGS and park officials release further monitoring data.
