Full Answer

Lo?ihi only began forming about 400,000 years ago. Several of the other Hawaiian volcanoes, such as Mauna Kea, Kohala and Haleakala, are about 1 million years old. The Ko?olau Range, Wai?anae Range and Ka?ena Ridge, all on O?ahu, are actually the remains of volcanoes that are 2 million to 5 million years old.

The Hawaiian Islands are a chain of islands, also known as an archipelago, located in the Pacific Ocean. There are eight main islands: Hawai?i (the Big Island), Maui, O?ahu, Kaua?i, Moloka?i, Lana?i, Ni?ihau and Kaho?olawe. The Hawaiian Islands are located above a volcanic hotspot, and all of the islands were formed through volcanic activity. As each underwater volcano erupted, the lava cooled and hardened, forming a land mass above sea level over millions of years.

    How are people affected by Kilauea?

    A:

    Kilauea, the largest volcano in the Hawaiian Islands, has affected the people who live in close proximity to it since humans first came to live on Hawaii. Kilauea is still active. It has been erupting constantly since 1983, according to the United States Geological Survey. Lava from the eruption has burned structures and buried roads, but there has been little loss of life as a result of Kilauea's eruption.
