Mauna Loa, meaning Long mountain in English, is the largest subaerial volcano in both mass and volume. It is one of the five volcanoes that form the Island of Hawaii in the Pacific ocean. Historically, Mauna Loa has been considered the largest volcano on the Earth. The volume of Mauna Loa is estimated at approx 18,000 cubic miles. It is an active shield volcano with its peak at the height of 120 feet which is lower than its neighbor Mauna Kea. The lava of Mauna Loa is tended to be non-explosive, silica-poor and very fluid.
