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.

An eruption of Mauna Loa volcano started at 11:30 p.m. on Sunday, November 27, 2022. Initial fissures covered the floor of Moku‘āweoweo caldera with new lava, but this area was mostly inactive by the time HVO field crews arrived after sunrise on Monday morning.

Mauna Loa eruption as viewed from Waikoloa at about 1:25am local time (HST). The eruption is occurring from the summit of the volcano, though lava has overflowed the caldera.

This reference map depicts the ongoing Kīlauea summit eruption on November 25, 2022. One eruptive vent (orange) is active within Halema‘uma‘u, on the western side of the crater floor. An adjacent pond (purple) is feeding lava to a larger lake (red) via a crusted-over tube.
