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. Patrick

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. At the base of the west vent lava was effusing at the lake level. There was no

Close-up view of active lava flow Halema‘uma‘u, February 24, 2021

In the morning of Tuesday, February 23, a new source of spatter appeared on flank of the active western fissure within Halema‘uma‘u at the summit of Kīlauea. It started to feed a short lava flow down the spatter cone and onto the crusted northwest margin of the lava lake. A field crew on Wednesday observed the flow to be active, and captured this photo through the lens of

On Wednesday, February 24, HVO scientists observed the Kīlauea summit eruption in Halema‘uma‘u from the west rim of the crater. In this photo, the active western fissure is marked by an incandescent skylight on the near side of the lava lake. A plume of sulfur dioxide and other volcanic gases rises constantly from the fissure as it effuses lava into the lake, which

The 2018 lower East Rift Zone eruption and summit caldera collapse marked the end of the 35-year-long Puʻu ʻŌʻō and 10-year-long summit lava lake eruptions, and the beginning of a new chapter in Kīlauea Volcano activity.  The volcano is continuing to behave in ways that are a response to the major events of 2018 and “the new normal” is yet to be defined.
