An eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Lava activity is currently confined within Halema‘uma‘u crater, in the closed area of Hawai‘i Volcanoes National Park.

HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park.

January 25, 2022 — Kīlauea summit eruption observations

Color photograph of volcanic vent
This telephoto view of the western vent in Halema‘uma‘u was captured on January 25, 2022. The Kīlauea summit eruption had been paused for several days, but the eruption resumed several hours before this photo was taken. Over the course of those hours, lava breakouts from the south side of the west vent spatter cone built a small lava shield (left). Laser rangefinder measurements indicated that the top of the main spatter cone (right) was standing approximately 21 meters (69 feet) above the surrounding lava flows at that time. USGS photo by L. Gallant.
Color photograph of lava flow
This telephoto image shows two lava falls in the Halema‘uma‘u lava lake at the summit of Kīlauea on January 25, 2022. These lava falls, along the southeastern edge of the active portion of the lava lake, were feeding a lava flow towards the south wall of Halema‘uma‘u crater. Laser rangefinder measurements indicated that the lava fall in the lower left of this frame was approximately 5 meters (16 feet) tall. USGS photo by M. Zoeller.

View looking westward toward the active lava lake within Halema‘uma‘u crater, taken during a helicopter overflight of Kīlauea summit on Tuesday, January 25, 2022, at 10:46 a.m. HST. Visitors can be seen at the teardrop-shaped Keanakāko‘i viewing area in the bottom, center of the image. Three sections of the old Crater Rim Drive can be seen on the left side of the photo. Part of this road (between the middle and upper sections) fell into the crater during 2018 collapse events. The upper segment of the road can be seen curving around the southwestern rim of the crater; it continues northward past the Uēkahuna overlook and former Jaggar Museum, an orangish-colored building in the upper right of the photo. The flanks of Mauna Loa can be seen in the background. USGS photo by J.M. Chang.

Emily Bryant, a geologist and field engineer visiting from the USGS Cascades Volcano Observatory, installs an upgraded webcam on the east rim of Halema‘uma‘u at the summit of Kīlauea. The active lava lake is in the western half of the crater, in the upper right portion of the photo. Bryant is here to help deploy and program instrumentation for network hardening, funded through the Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157) to support recovery and rebuilding activities in the wake of Kīlauea's 2018 summit collapse and lower East Rift Zone eruption.
