Like all Hawaiian volcanoes, Mauna Loa was created as the Pacific tectonic plate moved over the Hawaii hotspot in the Earth's underlying mantle. [10] The Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 3,700 mi (6,000 km)-long Hawaiian–Emperor seamount chain. [11]
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.
Of the 13 major summits of Hawaiʻi, Mauna Kea exceeds 4000 meters (13,123 feet) of topographic prominence, Haleakalā exceeds 3000 meters (9843 feet), Mauna Loa exceeds 2000 meters (6562 feet), six peaks are ultra-prominent summits with more than 1500 meters (4921 feet), and eight peaks exceed 1000 meters (3281 feet) of topographic prominence.
Mauna Loa is spewing sulfur dioxide and other volcanic gases. Lava is shooting 100 feet to 200 feet (30 to 60 meters) into the air as Hawaii's Mauna Loa, the world's largest active volcano, erupts ...
The Mauna Loa summit, cabins and high-elevation areas have been closed since early October when the summit first began "experiencing heightened unrest." Mauna Loa Observatory, located just outside ...
Why the Mauna Loa Eruption Is a Scientific Bounty Andrew Richard Hara - Getty Images. The world’s largest volcano has erupted for the first time since 1984, and it could prove a scientific bounty.
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 ).
