The fissure 8 lava flows of Kīlauea's 2018 lower East Rift Zone eruption meet the ocean at Pohoiki Bay, in the lower left corner of this image. Wave erosion of the 2018 lava flows along the coast contributes to sand accumulation that forms a beach at Pohoiki Bay. USGS image by K. Mulliken on March 4, 2021.

March 4 overflight of Kīlauea summit and East Rift Zone
Subtle steaming was visible at Pu‘u ‘Ō‘ō during HVO's overflight of Kīlauea on March 4, 2021. Steam is normally visible as the vent—which was active for more than 35 years—continues to cool, following the 2018 Pu‘u ‘Ō‘ō collapse.

Wide-angle view of Pu‘u ‘Ō‘ō, March 4, 2021
During a routine overflight of the Kīlauea East Rift Zone on March 4, HVO scientists visited the Pu‘u ‘Ō‘ō area to check for any significant changes in recent months. Their most notable observation was further accumulation of talus—rock collapse debris—in the crater that formed on April 30, 2018, as seen in this wide-angle photo.

Halema‘uma‘u lava lake, Kīlauea summit eruption—March 3, 2021
View of the Kīlauea summit lava lake taken from the west rim of Halema‘uma‘u at 12:21 p.m. HST on March 3, 2021. The western portion of the lava lake is active with lava being fed from the west vent. The eastern surface of the lava lake remains crusted over. SO2 emission rates are elevated at approximately 1000 t/d, as measured on March 3, 2021.

Halema‘uma‘u lava lake, Kīlauea summit eruption—March 3, 2021
The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active. Lava is entering the lake at a small inlet along the western lake margin, at the site of the western fissure. Active surface lava remains limited to the western portion of the lake. Scattered crustal foundering and small overflows were present on Tuesday, March 2, 2021. USGS photo by M.

Halema‘uma‘u lava lake, Kīlauea summit eruption—March 3, 2021
The western fissure in Halema‘uma‘u remains active, with incandescence visible in two small vent openings. The northeastern incandescent vent opening (right) has a narrow, drained lava channel extending down the flank of the cone. USGS photo taken by M. Patrick on March 2, 2021.

Halema‘uma‘u lava lake, Kīlauea summit eruption—March 3, 2021
The eastern portion of the lava lake in Halema‘uma‘u remains solidified at the surface. Numerous islands, previously drifting in the lake currents, are now locked in place. The remnants of a section of Crater Rim Drive, from the 2018 summit collapse, is visible in the lower right corner of the photo. USGS photo taken by M. Patrick on March 2, 2021.

February 26, 2021 — Kīlauea
On the afternoon of Friday February 26, 2021, the active west side of the lava lake at Halema‘uma‘u, Kīlauea Volcano, Hawaii, had numerous surface breakouts and foundering crust amid vigorous steaming due to the heavy rainfall. This view is looking to the east from the west side of the crater.
