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 history, with the largest recorded explosive eruptions having taken place in the 19th century.
Mauna Loa's most recent eruption began on November 27, 2022, and ended on December 13, 2022. It was the first eruption since 1984. [8] [9] No recent eruptions of the volcano have caused fatalities, but eruptions in 1926 and 1950 destroyed villages, and the city of Hilo is partly built on lava flows from the late 19th century.
The 2022 eruption of Mauna Loa was an episode of eruptive volcanic activity at Mauna Loa, the world's largest active volcano, located on Hawaiʻi island, Hawaiʻi. Mauna Loa began to erupt shortly before midnight HST on November 27, 2022, when lava flows emerged from fissure vents in Moku‘āweoweo (Mauna Loa's summit caldera ).

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 ...
By 2010, the Global Volcanism Program of the Smithsonian Institution had cataloged the assignment of a VEI for 7,742 volcanic eruptions that occurred during the Holocene (the last 11,700 years) which account for about 75% of the total known eruptions during the Holocene. Of these 7,742 eruptions, about 49% have a VEI of 2 or lower, and 90% have ...
An eruption on April 11 ejected a cloud of volcanic gas and ash that reached a height of 20 km (12 mi) and spread over an area of 108,000 km 2 (42,000 sq mi). [10] Pyroclastic flows from the eruption traveled up to 19 km (12 mi) away from the volcano.
