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.

This photo was taken the morning of November 23, 2022, at a moment when red molten material was visible in the inlet north of the west vent, which feeds into the lava lake. Incandescent material is intermittently visible in the inlet. USGS photo by K. Mulliken.

Uncrewed aircraft systems (UAS) flights on November 23, 2022, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The active lake surface is limited to the western portion of the crater.
