Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

There have been no major changes in the ongoing eruption at Kīlauea summit over the past day. All eruptive activity is confined within Halema‘uma‘u crater, in Hawai‘i Volcanoes National Park. The vent on the western wall and the fountain within the south-central portion of the lava lake remain the most vigorous and are producing the largest gas plumes. Sulfur dioxide (SO2

KWcam image taken on October 2, 2021, at 6 a.m. HST. This image shows the ongoing eruption within Halemaʻumaʻu crater at the summit of Kīlauea. The eruption began the afternoon of September 29, 2021, as fissures in the floor of the crater; this activity is generating a lava lake that is slowly filling the crater. USGS webcam image.

Lava continues to erupt from multiple vents on the base and west wall of Halemaʻumaʻu during the evening of October 2, 2021. Kīlauea summit sulfur dioxide (SO2) emission rates remain high and were estimated at around 20,000 tonnes per day the morning of September 30, 2021. This is significantly lower than the initial emission rates of 85,000 tonnes per day that were

Lava fountains from the western fissure vent in the Halema‘uma‘u crater wall, at Kīlauea's summit during the ongoing eruption. Sustained fountain heights from this fissure ranged from about 10–15 meters (33–49 ft) with occasional higher bursts of spatter. This video clip was recorded on October 2, 2021, from the western crater rim.

Kīlauea's summit eruption continues on the Island of Hawai‘i; Halema‘uma‘u west vent erupts lava into the lava lake, which was 226 m (741 ft) deep this morning, April 13. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear—monitor the eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.

The USGS recently published a data release that includes a three-dimensional model of Puʻuʻōʻō, on Kīlauea's East Rift Zone, and the collapse crater, constructed from aerial thermal images collected on 11 May 2018.  Structure-from-motion processing was used to create the model from the sequence of oblique images, and ground control using kinematic GPS was used to georegister the model.

One of the most interesting aspects of the current activity in Halemaʻumaʻu is the occasional oozing of lava around the edges of the entire crater while the lava surface is rising. Has that phenomenon been reported before in any accounts of previous Kīlauea activity?
