The Kilauea volcano erupted early this morning, prompting the Hawaiian Volcano Observatory to raise the alert level to “warning” and the aviation color code to red, indicating increased volcanic activity and potential danger.

The eruption, which began around 2:30 a.m. in the Halemaumau crater and summit caldera in Hawai’i Volcanoes National Park, was preceded by increased seismic activity below the summit starting around 2:00 a.m., according to HVO officials.

Webcam images from HVO captured fissures producing lava fountains and flows at the base of Halemaumau. In a statement, HVO stressed that “the initial stages of eruptions are dynamic.” However, activity is currently limited to the summit area and the risks will be reassessed as the situation develops.

The eruption occurred in a closed area of ​​Hawai’i Volcanoes National Park. Officials identified volcanic gas emissions – primarily water vapor (H2O), carbon dioxide (CO2) and sulfur dioxide (SO2) – as the main threat. Vog (volcanic smog) may occur in downwind areas, which can affect air quality and visibility. Vog-related information can be found at vog.ivhhn.org.

Lava flows are currently limited to Halemaumau and the eastern part of the summit caldera. Other dangers include volcanic glass particles such as Pele’s hair, which fall within a few hundred meters of the cracks and can be carried further by strong winds. These particles can cause skin and eye irritation. Residents and visitors are therefore advised to minimize exposure.

Other risks surrounding the caldera include unstable crater walls, ground cracks and rockfalls that can be triggered by sustained seismic activity. The Halemaumau crater area has been closed to the public since 2007.

Visitors are encouraged to check the Hawai’i Volcanoes National Park website for updates on access and safety measures. Residents should stay informed about air quality and minimize exposure to volcanic particles.
