Kīlauea's summit eruption continues on the Island of Hawai‘i; the west vent in Halema‘uma‘u erupts lava into the lava lake. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear and PPE—monitor the current eruption from within the closed area of Hawai&lsq
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.
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. Patrick.
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.
Another close-up view of the western fissure in Halema‘uma‘u, showing the incandescent lava upwelling at the inlet zone along the western lake margin. This photo was taken on March 2, 2021, in an area of Hawai‘i Volcanoes National Park that remains closed to the public due to safety reasons. USGS photo by M. Patrick.
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.
