Kīlauea is one of the island of Hawaii’s most active volcanoes, and one of the busiest in the world.

Hawai‘i Volcanoes National Park is once again earning its moniker. On Sept. 29, a little after 3 p.m. local time, one of Hawaii’s youngest and most active volcanoes at the Kīlauea summit began spewing lava and gas from its Halema’uma’u crater.

On the heels of Kīlauea’s last eruption that concluded just four months ago, the current activity is transpiring within a closed-off area of the national park, according to the U.S. Geological Survey. The rest of the park, however, remains open, with numerous vantage points of the eruption accessible along Crater Rim Trail.

The orange-hued radiance rising from the caldera took little time to attract the attention of tourists eager to witness “the plume of gas and steam by day and the lava glow after dark,” National Park Service officials said in a release.

“Viewing lava at the summit of Kīlauea is awe-inspiring,” Hawaiʻi Volcanoes National Park Superintendent Rhonda Loh said. “We continue to work with USGS scientists to receive the latest volcanic updates, and remind visitors that the eruptive activity and accessibility could change at any time. … We want to keep the park open for all to experience this new phase of volcanic activity, but we can only do so if visitors follow guidelines that keep everyone safe.”

Even though the immediate vicinity is closed to the public, the excess levels of volcanic gas emitted by the eruption remains a concern. Down wind of the volcano, a cocktail of carbon dioxide, sulfur dioxide and water vapor react with the atmosphere to create volcanic smog, or vog, which carries with it the potential “for airborne health hazards to residents and visitors,” the park’s release said.

Visitors who happen to be in the vicinity are urged to follow these safety tips.

Staff from the USGS and the Hawaiian Volcano Observatory continue to provide updates alongside real-time imagery of the eruption, with status notifications, live web cams, and planning tips available on the park website.
