After a 38-year pause, Mauna Loa erupted on Sunday night, November 27, 2022, at approximately 11:30 p.m. This new volcano activity is located at Mauna Loa’s summit at Moku’aweoweo Caldera at 13,681 feet or 4,170 meters above sea level.

Lava is clearly visible overnight in webcam views. This link will take you to the webcam. Note that lava activity is easier to observe in nighttime views verses daytime views as our following image illustrates from previous Kilauea eruptions.

At the time of writing on the morning of November 28, 2022,, lava is contained within the summit area and is not threatening downslope communities per this USGS hazard notification.

Mauna Loa is the second tallest summit on Hawaii (Big) Island, so it has a prominent presence on the island’s landscape. If you are visiting Hawaii Island, look to the summit of Mauna Loa and you might observe eruption activity — perhaps in a plume in the daytime or possibly a red/orange glow at night. According the this USGS report, this Mauna Loa eruption is visible from Kona.
