Climb Mauna Loa
Hawaii, United States
Mauna Loa is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaiʻi in the Pacific Ocean. Mauna Loa is the largest subaerial volcano in both mass and volume and has historically been considered the largest volcano on Earth. It is an active shield volcano, with a volume estimated at approximately 18,000 cubic miles (75,000 km3), although its peak is about 120 feet (37 m) lower than that of its neighbor, Mauna Kea. The Hawaiian name “Mauna Loa” means “Long Mountain”. Lava eruptions from Mauna Loa are silica-poor and very fluid; eruptions tend to be non-explosive and the volcano has relatively shallow slopes.
