This image shows an erupting fissure high on Mauna Loa's Northeast Rift Zone. Fountain heights of 20-25 meters (65-82 feet) were measured by HVO field crews on the morning of November 29, 2022. USGS image by L. Gallant.

An erupting fissure high on Mauna Loa's Northeast Rift Zone was issuing multiple lava flows on the morning of November 29, 2022. Fountain heights of 20-25 meters (65-82 feet) were measured by HVO field crews. A gas plume is rising off of the fissure and partially obscuring Mauna Kea in the background of the image.

A Hawaiian Volcano Observatory geologist documents a lava flow from the Northeast Rift Zone of Mauna Loa the morning of November 29, 2022. The ‘a‘ā lava flow, on the northeast flank of Mauna Loa, is several feet thick. 'A'ā flows have a rough rubbly surface composed of broken lava blocks called clinkers.

Aerial view of Mauna Loa summit with Lua Hou in the foreground followed by Lua Hohonu, South Pit, and Mokuʻāweoweo summit caldera. A small dusting of snow covers the ground east of the summit. The steaming fissure was active during the beginning of the eruption, but this morning the lava in the summit caldera had already cooled to a black color.
