MAUNA LOA, HAWAII
Mauna Loa is situated on the island Hawaii, the most southerly of the Hawaiian islands. It is the largest active volcano of the world, covering almost half of the island and rises some 9000 metres from the ocean floor. From sea level it is 4170 meters high. The Hawaiian Islands are all volcanic islands that were formed over the past 75 million years as the Pacific plate passed over a mantle hot spot or mantle plume.
