Mauna Loa is the largest volcano on earth. It is an active shield volcano, with a volume estimated at approximately 18,000 cubic miles (75,000 km³),[1] although its peak is about 120 feet (37 m) lower than that of its neighbor, Mauna Kea, another of five volcanoes that form the Island of Hawaiʻi. The Hawaiian name "Mauna Loa" means "Long Mountain". Lava eruptions from it are silica-poor, thus very fluid: and as a result eruptions tend to be non-explosive and the volcano has extremely shallow slopes.
The volcano has probably been erupting for at least 700,000 years and may have emerged above sea level about 400,000 years ago, although the oldest-known dated rocks do not extend beyond 200,000 years.[2] Its magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian island chain for tens of millions of years. The slow drift of the Pacific Plate will eventually carry the volcano away from the hotspot, and the volcano will thus become extinct within 500,000 to one million years from now.

None. Mauna Loa, the significant volcano on the "massive island" of Hawai'i, changed into formed by ability of something said as "warm-spot" volcanism. this happens at the same time as a plume of magma from the mantle reaches the Earth's crust. There are various circumstances of warm spots all over the world, notwithstanding the Hawai'ian islands and the Emperor seamounts are the most prominent. different examples might want to be Iceland and the Yellowstone section in Wyoming.
