The Hawaiian volcanoes could be said to be more creative than destructive.
Volcanic activity built this chain of islands, and the only known deadly eruptions killed a division of the Hawaiian army—in 1790—and one other person—in 1924. The 1969 eruption took no lives.
Four shield volcanoes make up the island of Hawaii. Mauna Kea first grew to 13,825 feet (4,200 meters) above water. The smaller volcanoes, Kilauea and Haulalai, then sprouted from its sides.
Further internal volcanic activity then created Mauna Loa, 13,678 feet (4,169 meters) in the air. The mild nature of these volcanoes allowed the United States to open them, and Haleakala on nearby Maui, as the Hawaii Volcanoes National Park.
Since 1911, the Hawaiian Volcano Observatory on Hawaii has gathered an immense amount of data and information on volcanology, the study of volcanoes.
