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 ).
Kilauea began erupting around 2:30 a.m. Monday morning local time at the base of the Halemaumau Crater within the summit caldera after elevated seismic activity was detected overnight.
English: When Hawaii’s massive Mauna Loa volcano began erupting for the first time in nearly four decades late on November 27, 2022, lava initially spilled from the Moku’āweoweo crater at the mountain’s summit. But by the next morning, activity had migrated to a cluster of four fissures northeast of the summit.
“Mauna Loa erupting at sunrise is literally the most amazing thing I’ve ever seen.”
The uptick in activity around Kīlauea began on Jan. 15 and, according to the U.S. Geological Survey, has remained safely in the mountain’s caldera in Hawai‘i Volcanoes National Park.
A survey of the caldera by a remote operated vehicle in August 2022 found continuing signs of volcanic activity. [91] In August 2022, a NASA report on the January 2022 eruption of Hunga Tonga–Hunga Haʻapai stated, "The huge amount of water vapor hurled into the atmosphere, as detected by NASA’s Microwave Limb Sounder, The excess water ...
The volcano also erupted in June about a mile south of Kilauea caldera, marking the first eruption in that region of the volcano in about 50 years. The last one took place in December 1974. The ...
A Hawaiian eruption is a type of volcanic eruption where lava flows from the vent in a relatively gentle, low level eruption; it is so named because it is characteristic of Hawaiian volcanoes. Typically they are effusive eruptions , with basaltic magmas of low viscosity , low content of gases, and high temperature at the vent.
