According to the Hawaiian Volcano Observatory (HVO), Kilauea’s eruption began around 3:15 p.m. HST Sunday after increased earthquake activity and changes in ground deformation patterns at Kilauea’s summit began to occur.
Webcam video and field reports indicated the eruption began within Halema’uma’u crater and on the downdropped block in Kilauea’s summit caldera within Hawaii Volcanoes National Park, according to the HVO.
The volcano’s alert level was then raised from Watch to Warning, and the aviation color code was changed from Orange to Red.
But on Monday, officials with the HVO said conditions were beginning to stabilize, and alert levels at the volcano had been changed back to a Watch while the aviation color code was changed back to Orange.
The HVO said these changes were made because the style of eruption and fissure location stabilized, the initial extremely high effusion rates declined, and no infrastructure was being threatened.
In addition, the associated hazards from the volcano were confined to the closed area established by Hawaii Volcanoes National Park.
Officials said they expect Kilauea’s summit eruption to continue and remain confined to Kilauea’s caldera within the national park. The HVO said it doesn’t see any indications of activity migrating elsewhere on Kilauea and expects the eruption to remain confined to the summit region.
However, conditions are being continuously monitored and will report significant changes.
Geologists said Pele's hair and other lightweight volcanic glass fragments from the lava fountains were expected to fall downwind of the fissure vents and dust the ground within a few hundred yards of the vents, according to the HVO.
Kilauea last erupted in June, and its first eruption of 2023 began in January.
That eruption lasted until the beginning of March. However, that eruption was considered brief compared to previous eruptions, which lasted about three months.

The HVO has several cameras livestreaming activity from different areas of Kilauea, which operate 24 hours a day.
