Mauna Loa erupts after longest quiet period in recorded history

Mauna Loa volcano began erupting in Moku‘āweoweo Caldera on November 27, 2022, at approximately 11:30 p.m. This is the first time Mauna Loa has erupted in 38 years. By 6:30 a.m. on November 28, the eruption had migrated to the upper Northeast Rift Zone. There is a visible gas plume from the erupting fissure fountains and lava flows. Mauna Loa continues to erupt and lava has moved from the summit to the Northeast Rift Zone where, according to the USGS website, it is flowing from one fissure, as of 1:30 p.m. on November 28.

Officials said the flow is not threatening any communities. No property is at risk currently. Residents with questions about emergency response and resources that may be available to assist those at risk should consult the Hawai’i County Civil Defense.

Mauna Loa also erupted from the northeast in 1984.That time, lava headed toward Hilo but stopped a few miles short of the city. Historically, each Mauna Loa eruption has lasted a few weeks. Ken Hon, scientist-in-charge at the Hawaiian Volcano Observatory, expects the current eruption to follow this pattern.
