This photograph of Kīlauea's ongoing middle East Rift Zone eruption was captured during a Hawaiian Volcano Observatory helicopter overflight during the morning of September 17, 2024. This photo was taken at 8:11 am H.S.T.

The S2cam was deployed on September 17, 2024, to monitor the Kīlauea middle East Rift Zone eruption. The webcam is located just east of Nāpau Crater, where the eruption is occurring, and looks to the southwest. USGS webcam image.

A benchmark on Kīlauea being surveyed by GPS campaign instruments. The metal disk on the ground beneath the tripod is the benchmark, which is cemented to the lava flow surface. During annual GPS surveys, measurements are made on the benchmarks to allow for comparisons to previous surveys. USGS photo by A. Ellis.

USGS Hawaiian Volcano Observatory geologists collected a sample of the middle East Rift Zone Kīlauea eruption in Nāpau Crater, within a closed area Hawaiʻi Volcanoes National Park. Geologists put molten lava into a metal bucket and rapidly quench it with water.

This photograph of Kīlauea's ongoing middle East Rift Zone eruption was captured during a Hawaiian Volcano Observatory helicopter overflight during the morning of September 17, 2024. This low-angle view looking southwest shows three lava fountains; the tallest is approximately 10 meters (30 feet) high.

This reference map depicts fissures and lava flows from the Kīlauea middle East Rift Zone eruption on Tuesday, September 17, 2024. The presented data are current as of the final Hawaiian Volcano Observatory helicopter overflight of the day, which occurred at approximately 10:30 a.m.

This reference map depicts the approximate location of the fissures that erupted from the Kīlauea middle East Rift Zone, likely between approximately 9:00 and 10:00 p.m. HST on Sunday 15, 2024, in a remote and closed area of Hawaiʻi Volcanoes National Park. Small lava pads erupted from two fissure segments in a couple hundred meters (hundred yards).

Another aerial view of the small lava flows erupted by Kīlauea over about an hour on September 15, 2024. This eruption took place on the remote middle East Rift Zone, within Hawaiʻi Volcanoes National Park. Although the eruption was over during the USGS Hawaiian Volcano Observatory morning overflight, volcanic gas emissions were continuing.

A brief, small eruption occurred on the middle East Rift Zone of Kīlauea late on September 15. The eruption produced two small pads of lava just west of Nāpau Crater, which is west (uprift) of the former Pu‘u‘ō‘ō eruption site. USGS photo by M. Patrick.

During a USGS Hawaiian Volcano Observatory overflight at approximately 10:30 a.m. HST on September 16, geologists observed freshly erupted lava west of Nāpau Crater on the remote middle East Rift Zone of Kīlauea, within Hawaiʻi Volcanoes National Park. This eruption likely occurred between approximately 9–10 p.m. HST on September 15.

During a USGS Hawaiian Volcano Observatory overflight at approximately 10:30 a.m. HST on September 16, geologists observed steam rising above freshly erupted lava west of Nāpau Crater on the remote middle East Rift Zone of Kīlauea, within Hawaiʻi Volcanoes National Park. This eruption likely occurred between approximately 9–10 p.m.

The map on the left shows recent deformation at Kīlauea over the timeframe of August 9–21, 2024. Data were acquired by the European Space Agency's Sentinel-1A satellite. 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.

USGS scientists made a routine visit to the summit of Kīlauea for maintenance work on a webcam and general observations. The weather offered clear views of Kaluapele (the summit caldera), and only minor outgassing from several spots on the caldera floor. USGS photo by M. Patrick.
