The summit eruption of Kīlauea volcano on Hawaii's Big Island has paused, as reported by the Hawaiian Volcano Observatory. The fiery spectacle that entranced visitors at the Hawai‘i Volcanoes National Park, ceased its activity at about 8:40 p.m. last Friday, the halt marking the third since its commencement on December 23, 2024. While the lava fountains and flows within Halemaʻumaʻu Crater are no longer active, a faint glow remains visible through cracks in the lava lake's crust, continuing to attract spectators.
Despite the pause in eruptive behavior, significant changes within the volcano's structure have occurred. According to a statement obtained by Kauai Now News, the southern vent, which was the epicenter of the eruption, has formed an internal structure that may prevent the lava from receding back into the vent. Seismic activity decreased as the eruption subsided, and the deflation that began on December 29, 2024, is ongoing, though it is expected to slow down or potentially reverse into an inflationary phase soon.
The Hawaiian Volcano Observatory noted that crustal overturns are likely to continue in the hours following the pause, as indicated by the visible glow in livestream footage. Fountaining has ceased, and seismic activity at the summit is low, with only a few small earthquakes detected. However, the observatory continues to monitor the volcano closely and is in regular contact with Hawai‘i Volcanoes National Park and Hawai‘i County Civil Defense.
Volcanic gas emissions remain high, continuing to present a natural hazard during the period of volcanic activity. A plume of gas, primarily consisting of water vapor, carbon dioxide, and sulfur dioxide, was observed rising above the caldera and drifting southwest, as reported by Big Island Now. Thursday's measurement recorded sulfur dioxide emissions at around 30,000 tonnes per day, which could impact individuals with pre-existing health conditions.
For potential visitors and those already on the Big Island, the opportunity to witness the aftermath of a volcanic eruption remains a point of interest. Reports from Big Island Now describe the nighttime glow, even in the absence of active lava flows. As the situation evolves, the park's website is recommended for the latest visitor information and updates on conditions. Currently, Kīlauea's alert level is at watch, and its aviation color code is orange, indicating heightened or escalating unrest with an increased potential for eruption, though no immediate hazards are anticipated.
