Photo and Video Chronology — Kīlauea East Rift Zone webcam maintenance and new Kīlauea interferogram

By Hawaiian Volcano Observatory October 23, 2024

USGS Hawaiian Volcano Observatory scientists conducted maintenance on a webcam on the East Rift Zone of Kīlauea, where a recent interferogram shows magma continues to accumulate underground. 

October 23, 2024 — Routine maintenance on Kīlauea East Rift Zone webcam

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. USGS photo by M. Patrick.

An HVO 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.

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.

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.

October 23, 2024—InSAR image of Kīlauea middle East Rift Zone deformation

Color map showing ground deformation on a volcano

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. The symbol in the upper left indicates the satellite's orbit direction (arrow) and look direction (bar). The round feature north of Nāpau and Makaopuhi Craters on the middle East Rift Zone indicates ground surface inflation over this time period as magma accumulates underground near the recent September 15–20, 2024, eruption site. Fringes at Kaluapele are due to new topography created by past lava flows, that has not yet been incorporated into our digital elevation model (DEM).
