This is a list of volcanic eruptions from Mauna Loa, an active shield volcano in the Hawaiian Islands that last erupted in 2022. These eruptions have taken place from the main caldera and fissures along rift zones. They are generally fluid (VEI-0) Hawaiian eruptions but more violent eruptions have occurred throughout Mauna Loa's eruptive ...
Before 2022, Mauna Loa had last erupted in March 1984, in a 22-day event similarly concentrated in the volcano's Northeast Rift Zone. [6] The 2022 eruption was the volcano's 34th eruption since 1843, when volcanic activity at Mauna Loa began to be continuously recorded, but only the third eruption since 1950.
Mauna Loa erupted at 11:30 p.m. local time Sunday (4:30 a.m. ET Monday), the U.S. Geological Survey said. It was the first eruption since 1984, according to its Hawaii Volcano Observatory daily ...
Mauna Loa is a shield volcano with relatively gentle slopes, and a volume estimated at 18,000 cubic miles (75,000 km 3), [5] although its peak is about 125 feet (38 m) lower than that of its neighbor, Mauna Kea. [6] Lava eruptions from Mauna Loa are silica-poor and very fluid, and tend to be non-explosive.
The first eruption in 38 years of Mauna Loa, the world’s largest active volcano, is drawing visitors to Hawaii Volcanoes National Park, which is open 24 hours a day. ... Mauna Loa last erupted ...
In the U.S. and its territories, there are 161 potentially active volcanoes, including Mauna Loa. According to the U.S. Geological Survey, there are around 1,350 potentially active volcanoes ...
Geologists suggested that "pulses" of magma entering Mauna Loa's deeper magma system may have increased pressure inside Kīlauea and triggered the concurrent eruptions. [28] Mauna Loa began erupting on November 27, 2022, during Kīlauea's ongoing eruption, the first time since 1984 that both volcanoes were simultaneously erupting.
Lava from Mauna Loa, which began erupting Nov. 27 after being quiet for 38 years, was 1.76 miles (2.83 kilometers) from Saddle Road, also known as Route 200 or Daniel K. Inouye Highway, the U.S ...
