Mauna Loa fissure eruption and lava flow
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.
