Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

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.

Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

With permission from Hawa‘i Volcanoes National Park, Hawaiian Volcano Observatory (HVO) scientists continue to monitor the ongoing eruption within Halema‘uma‘u, at Kīlauea's summit. No significant changes have occurred over the past 24 hours. When HVO geologists are not in the field, webcameras, such as one pictured here, allow HVO staff and the public to monitor the

Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

The eruption in Halema‘uma‘u, at Kīlauea's summit, continues as of the evening of October 2, 2021. From the south rim of Halema‘uma‘u, this image shows at least three fountaining sources in the crater. Hawaiian Volcano Observatory scientists monitoring the eruption today noted that spatter from the fountain near the southeast edge of the island in the center of the lava

Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

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

Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

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.

Vents on the western wall of Halema‘uma‘u crater

This telephoto image shows two vents that formed on the western wall of Halema‘uma‘u crater during the current eruption of Kīlauea, which began on September 29, 2021. The photo was taken from the southern rim of Halema‘uma‘u crater at 9:02 a.m. HST on Oct. 1, 2021, in an area of Hawai‘i Volcanoes National Park that remains closed to the public due to safety reasons.

Kīlauea summit eruption in Halemaʻumaʻu crater - October 1, 2021

A helicopter overflight the morning of October 1, 2021, provided aerial views of the eruption within Halema‘uma‘u, at Kīlauea's summit. This view, looking to the west, shows an active lava fountain located within the south-central part of the lava lake. This fountain is only a few meters (yards) high. USGS photo by D. Downs.

Kīlauea summit eruption in Halemaʻumaʻu crater - October 1, 2021

Aerial image looking to the west of the large island that is floating within the middle of the lava lake in Halema‘uma‘u, at Kīlauea's summit. There are several vents with fountains reaching to just a few meters (yards) high. One of the vents along the eastern margin of the island has started to form spatter ramparts to enclose it.

Kīlauea summit eruption in Halemaʻumaʻu crater - October 1, 2021

Aerial view of the active lava lake and vents within Halema‘uma‘u crater, at the summit of Kīlauea. This view is looking to the northwest. Since the start of the eruption on September 29, 2021, much of the topography of the previous lava lake (active between December 2020 and May 2021) has been covered with newer lava; however, features of the previous lava lake remain,

Kīlauea summit eruption in Halemaʻumaʻu crater - October 1, 2021

Aerial photo taken during a morning overflight on October 1, 2021, and looking at the west end of the lava lake within Halema‘uma‘u crater, at the summit of Kīlauea. The west vent that is feeding this part of the lava lake is visible; the base of this vent was well above the lava lake when it opened on the afternoon of September 29, 2021. Since then, the lava lake has

October 1, 2020—Kīlauea summit eruption thermal maps

A helicopter overflight on October 1, 2021, at approximately 10 a.m. HST allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The scale of the thermal map ranges from blue to red, with blue colors indicative of cooler temperatures and red colors indicative of warmer temperatures. The dimensions of the new lava lake

Kīlauea summit eruption in Halemaʻumaʻu crater - October 1, 2021

Aerial image looking to the southwest and showing fissures within Halema‘uma‘u, at Kīlauea's summit, producing lava fountains within the southern and south-central part of the lava lake. These lava fountains are less energetic than when the eruption started on September 29, 2021, but are still spattering to heights of about 5 meters (16 ft) or less. USGS photo by D. Downs
