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.
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.
The eruption has been occurring within a closed area of Hawai'i Volcanoes National Park. Volcanic gas is said to be the primary hazard of concern, but the emissions have generally been modest and ...
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.
Hawaii’s Kilauea volcano is currently spewing fiery red-orange lava up to 250 feet high from its north vent – in what’s called "Episode 8" of the ongoing Halemaʻumaʻu eruption.
The world's largest active volcano, Mauna Loa, erupted late Sunday night after laying dormant for nearly 40 years, the U.S. Geological Service's (USGS) volcanic activity service reported.
