This image shows spatter that was thrown up onto the Nāpau Crater trail to the northeast of the September 2024 middle East Rift Zone lava falls that spilled over the western rim of Nāpau Crater. Boot for scale. USGS photo by K. Lynn.

A USGS Hawaiian Volcano Observatory geologist observes a fissure from the September 15–20, 2024, Kīlauea East Rift Zone eruption that occurred in and near Nāpau Crater. This photo was taken on November 25, where the first fissure opened, uprift (west) of Nāpau Crater. Pu‘u‘ō‘ō is visible on the skyline in the upper right. USGS photo taken by L. DeSmither.

With permission from Hawai‘i Volcanoes National Park, team of USGS Hawaiian Volcano Observatory geologists visited the site of the September 2024 Kīlauea middle East Rift Zone eruption. On November 25–26, they surveyed, sampled, and documented the new volcanic fissures and features, which formed west of and in Nāpau crater from September 15–20, 2024.

A USGS Hawaiian Volcano Observatory geologist displays pieces of lava spatter on their hand that were collected for geochemical analyses. The volcanic glass, erupted from a fissure on the East Rift Zone of Kīlauea in September 2024, was twisted in the air while still molten to form unique shapes. USGS photo taken on November 25, 2024, by L. DeSmither.

Lava trees stand in the middle of a lava flow from the September 2024 eruption on Kīlauea’s East Rift Zone. The height of these lava trees represents the height of the lava flow at the time it was emplaced, with the lava cooling as it came into contact with the tree trunks.

Examples of Hawaii geologic maps. The lefthand map is a USGS Hawaiian Volcano Observatory map created on September 17, 2024, within hours of remote sensing (helicopter overflight) of the eruption that occurred from September 15–20, 2024.

High winds at the summit of Mauna Loa ripped several solar panels from their masts, damaging them. HVO staff performed a partial fix to the site to bring the summit webcams back online November 7, 2024. USGS photo by M. Patrick.

HVO staff inspected the radio telemetry site at the summit of Mauna Loa and found wind damage to several components. Mauna Kea is in the background. USGS photo by M. Patrick.

Mauna Loa summit webcams have been down for several months due to wind damage at the radio telemetry site. On November 7, 2024, HVO staff visited the site and performed a partial fix that brought the webcams back online. Further visits will be needed to repair damaged solar panels. USGS photo by M. Patrick.

This map shows recent deformation at Kīlauea over the timeframe of October 6–18, 2024. Data were acquired by the European Space Agency's Sentinel-1 satellites. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation. Each color cycle represents 2.8 cm (1.1 in) of ground motion.

A view of vegetation that has appeared along the rim of Pu‘u‘ō‘ō since 2018, and the red ash along the rim that was deposited during the 2018 collapses. Handheld radio for scale. USGS photo by M. Patrick.

A USGS Hawaiian Volcano Observatory geologist inspects the R3cam webcam enclosure, which had a small amount of water accumulation in recent months that obscured the image. This area of the volcano experiences very high rainfall. Drying out the enclosure and adding fresh desiccant should keep the camera views clear in the future. USGS photo by M. Patrick.

A view into Pu‘u‘ō‘ō's crater from the south rim. The white layers represent numerous lava flows and spatter-fed flows formed during periods of high fountaining in the 1980s. The crater floor collapsed in 2018, and dropped by more than 300 meters (yards). Subsequent collapses have filled the deepest part of the crater. USGS photo by M. Patrick.

Another view of moss and ferns along the rim of Pu‘u‘ō‘ō, on Kīlauea's East Rift Zone. The red ash originates from collapses within the crater during 2018. USGS photo by M. Patrick.

This photo looks west along the south rim of Pu‘u‘ō‘ō. Red ash from the collapses during 2018 fills depressions in the lava flows, allowing moss and small ferns to grow. Green vegetation such as this was not observed by geologists near the rim during the 1983-2018 eruption, presumably due to high gas concentrations. USGS photo by M. Patrick.

The R3cam is a webcam on the east flank of Pu‘u‘ō‘ō, and it monitors areas downrift of Pu‘u‘ō‘ō. Given the recent eruptive activity in nearby Nāpau crater, this webcam is essential for detecting any changes that could occur in the area during future unrest. Today, USGS geologists visited to site to dry out the camera enclosure and add new desiccant.

An area of forest continues to burn in a remote area on the south rim of Nāpau Crater following the recent eruption on Kīlauea’s middle East Rift Zone, within Hawai‘i Volcanoes National Park. Beginning around 4 p.m. HST on October 6, a smoke plume from the burning vegetation became visible in HVO webcam imagery, and intermittent incandescence was seen overnight.

This aerial photo of Nāpau Crater, looking south, shows the lava flows (gray) from the recent Kīlauea middle East Rift Zone eruption. Along the south rim of the crater (background of image), smoke plumes are visible from a small wildfire that continues to burn in a remote area of Hawai‘i Volcanoes National Park. USGS photo taken by L.

On the middle East Rift Zone of Kīlauea, a recent eruption covered a large portion of the Nāpau Crater floor with new lava—dark gray lava near center of image. This eruption started a forest fire that continues to burn vegetation along the southern rim of Nāpau Crater. Photo view looking northwest with Kānenuiohamo visible in the upper left.

Kīlauea volcano is not erupting. An ongoing wildfire in the vicinity of the recent eruption area near Nāpau Crater in Hawai‘i Volcanoes National Park has been intermittently visible in HVO webcam imagery.
