The world's largest active volcano has erupted in Hawaii for the first time in nearly four decades, officials said. Mauna Loa erupted at 11:30 p.m. local time Sunday night (4:30 a.m. EST on Monday), the United States Geological Survey said. It was the first eruption since 1984, according to the Hawaii Volcano Observatory daily update, issued by the U.S. Geological Survey. Residents at risk from Mauna Loa lava flows were warned to "review preparedness and refer to Hawai‘i County Civil Defense information for further guidance." It is one of six volcanoes in the state of Hawaii, according to the U.S. Geological Survey.

Hawaii's Mauna Loa, the world's largest active volcano, erupted late Sunday night local time. "If the eruption remains in Moku'āweoweo [the summit caldera], lava flows will most likely be confined within the caldera walls.

Mauna Loa is located on Hawaii's southernmost island — Hawaii — and has an elevation of more than 13,600 feet. It's the world's largest active volcano, and most recently erupted in 1984.

Nov 28 (Reuters) - An eruption began in the summit caldera of Hawaii's Mauna Loa, the world's largest active volcano, on Sunday night, the U.S. Geological Service's (USGS) volcanic activity service said. "At this time, lava flows are contained within the summit area and are not threatening downslope communities," the notification said. However, the notification warned, based on previous events, that the early eruption stages of this volcano can be very dynamic and the location and advance of lava flows can change rapidly. The volcano alert level was upgraded from an "advisory" to a "warning." The notification added that the Hawaiian Volcano Observatory (HVO) would conduct aerial reconnaissance as soon as possible to assess hazards and better describe the eruption.

The Clean Air Task Force commissioned a non-profit geothermal organization, the Hot Rock Energy Research Organization, and an international clean energy consultancy, LucidCatalyst, to estimate the levelized cost of commercial-scale superhot rock electricity. Graphic courtesy Clear Air Task ForceRegular versus superhot geothermalWhile energy from superhot rocks is not being used now, geothermal energy is being used in a few places where super-hot temperatures exist close to the surface of the earth. But accessing superhot rock energy involves tapping into hotter, dry rock — which is everywhere, but sometimes far beneath the surface.

Beyond Iceland, Italy, Japan, New Zealand and the United States are leaders in superhot rock geothermal, according to Friðleifsson.

"It will take public and private investment similar to those being allocated to nuclear, carbon capture, and hydrogen fuels," Hill told CNBC.
