For more information on gas hazards at the summit of Kīlauea, please see. As SO 2 is released from the summit, it reacts in the atmosphere to create the visible haze known as vog (volcanic smog) that has been observed downwind of Kīlauea. During Kīlauea summit eruptions, the high level of volcanic gases-primarily water vapor (H 2O), carbon dioxide (CO 2), and sulfur dioxide (SO 2)-being emitted is the primary hazard of concern, as this hazard can have far-reaching effects downwind. Hazard Analysis: Eruptive activity is occurring on the downdropped block and Halemaʻumaʻu crater, within Kīlauea's summit caldera and in the closed area of Hawaiʻi Volcanoes National Park. Measurements from continuous gas monitoring stations downwind of Puʻuʻōʻō in the middle East Rift Zone-the site of 1983–2018 eruptive activity-remain below detection limits for SO 2, indicating that SO 2 emissions from Puʻuʻōʻō are negligible. Rift Zone Observations: No unusual activity has been noted along the East Rift Zone or Southwest Rift Zone steady rates of ground deformation and seismicity continue along both. Emission rates appear to be lower this morning, but have not been confirmed by addtional measurments at this time. yesterday, HVO staff measured preliminary sulfur dioxide (SO 2) emission rates of up to 100,000 tonnes per day or more. Volcanic gas emissions in the eruption area are elevated between 4 and 5 p.m. Summit seismic activity is dominated by eruptive tremor (a signal associated with fluid movement). Summit Observations: Summit tilt has remained deflationary over the past 24 hours. A live-stream video of the eruption is available at. The laser rangefinder is aimed at a western portion of Halema‘uma‘u crater, not near the new eruptive activity, and recorded about 2.5 m (8 feet) of new lava added to that portion of the crater floor. Lava fountain heights have decreased since the eruption onset, but remain up to about 10-15 meters (32-50 feet) high this morning. Lava erupted from fissures on the downdropped block is flowing in a westward direction towards Halema‘uma‘u crater, covering much of the surface with active lava. Effusion rates appear down from initial eruptive rate, but remain high. The line of vents stretches approximately 0.8 miles (1.4 km), from the eastern part of Halema‘uma‘u crater floor extending into the east wall of the downdropped block. Halemaʻumaʻu Lava Lake Observations: Multiple minor fountains remain active in the eastern portion of Halema‘uma‘u crater floor and on the downdropped block within Kīlauea's summit caldera. No unusual activity has been noted along Kīlauea’s East Rift Zone or Southwest Rift Zone.

Eruptive activity is confined to the downdropped block and Halemaʻumaʻu crater within Kīlauea's summit caldera.
