Scientists had been on alert because of a recent spike in earthquakes at the summit of the volcano, which last erupted in 1984.
The USGS warned residents at risk from Mauna Loa lava flows should review their eruption preparations. “Right now it’s just entertainment, but the concern is” it could reach populated areas, he said. “You could see it spurting up into the air, over the edge of this depression,” Mench said. Mench and his wife, Ellie, ventured out to film the eerie red glow cast over the island, watching as lava spilled down the volcano’s side. Gunner Mench, who owns an art gallery in Kamuela, said he had awoken shortly after midnight and seen an alert on his phone about the eruption.

Rift zones are where the mountain rock is cracked and relatively weak, making it easier for magma to emerge. The USGS said the eruption had migrated to a rift zone on the volcano’s north-east flank.

Volcanic gases wafting out of the vents, primarily sulfur dioxide, are also harmful. Officials urged the public to stay away, given the dangers posed by lava, which is shooting 100 to 200ft (30 to 60 metres) into the air out of three separate fissures estimated to be 1 to 2 miles (1.6 to 3.2km) long. “We don’t know where the flow is going, we don’t know how long it’s going to last.” “I think everybody should be a little bit concerned,” he said. He said he had seen three Mauna Loa eruptions in his lifetime and stressed the need for vigilance. Ken Hon, scientist-in-charge at the Hawaiian Volcano Observatory, said air quality could deteriorate while the eruption lasted, which scientists expect will be about one or two weeks if the volcano follows historical patterns.īobby Camara, a lifelong Big Island resident who lives in Volcano village, said everyone across the island should keep track of the eruption.
