The youngest volcano in Hawaii is Lo?ihi. The summit of this volcano is located approximately ½ mile under the ocean's surface, about 20 miles southeast of the Big Island of Hawai'i.Know More
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.Learn More
A volcano is a place where molten rock seeps or erupts from beneath the crust. Most volcanoes develop in the oceans, but some occur on land. When the molten rock, which is called lava, erupts with force, large, cone-shaped mountains form, which are also called volcanoes.Full Answer >
The lava from a volcano ranges in temperature from 570 to 2,120 degrees Fahrenheit. In comparison, water boils at 212 F, and a pizza oven is generally 500 to 600 F.Full Answer >
Popular volcanic mountain names are Mount St. Helens in the United States mainland, Mauna Loa in Hawaii, Mount Rainier in Washington, Mount Edziza in British Columbia and Hoodoo Mountain in Canada. Many of the highest volcanoes are located in Chile and Argentina, such as Ojos del Salado, Tacora, Tromen, Copahue and Risco Plateado.Full Answer >
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.Full Answer >
