The Hawaiian Island Chain
The Hawaiian Islands include eight major islands (Hawaii, Maui, Oahu, Kahoolawe, Lanai, Molokai, Kauai and Ni'ihau), and over 200 minor islands in the Pacific Ocean.
All islands in the Hawaiian Island chain were created through volcanic activity on the sea floor, by a "hot spot" under the Pacific Plate.
As the ocean floor moved slowly over this hot spot, continuous upwellings of lava over 70 million years created volcanoes that moved along the plate, resulting in a string of over 80 volcanoes that became the Hawaiian Islands.
As these volcanoes lifted, grew and cooled, the largest appeared above the surface and became basalt islands with gentle, sloping volcanoes and lava flows.
Moving up the chain from Hawaii, the islands become older and less active volcanically. There are currently three active volcanoes in Hawaii: Kilauea, Mauna Loa (dormant) and Lohi, a submerged island south of Hawaii. Haleakala, on Maui, last erupted in the 18th century.
Today, Hawaii Volcanoes National Park provides stunning views of Mauna Loa, the largest volcano on earth, as well as of Kilauea's eruptions, offering a fascinating glimpse of the island's fiery origins.
