Hawai‘i Volcanoes National Park displays the results of 70 million years of volcanism, migration, and evolution -- processes that thrust a bare land from the sea and clothed it with unique ecosystems, and a distinct human culture. The park highlights two of the world's most active volcanoes, and offers insights on the birth of the Hawaiian Islands and views of dramatic volcanic landscapes. The major inhabited Hawaiian Islands were formed during the past 5 million years by the intermittent outpouring of lava from the floor of the Pacific Ocean. According to the theory of plate tectonics, the island of Hawai'i sits on, and is almost in the middle of, the Pacific Plate, a giant jigsaw piece of the Earth's crust that is moving slowly (about four inches per year) in a northwesterly direction. As Janet Babb explains in Hawai'i Volcanoes—The Story Behind the Scenery, "Heat from a relatively stationary hot spot deep within the Earth's mantle creates magma (molten rock) that rises through the overlying Pacific plate and erupts on the ocean floor. After thousands of eruptions, an island builds a rocky mass above sea level." Like a slow-paced assembly line, the plate, moving over the hot spot, has created a succession of islands in the Hawaiian Ridge that extends all the way to Midway and Kure, more than 1,500 miles (2,414 km) from where it began 30 to 35 million years ago. The Hawaiian Islands are but mere tops of gigantic mountains rising from the floor of the ocean. The newest of these islands, Hawai'i, is relatively young, geologically speaking. The oldest rocks above sea level are less than one million years old. The Island of Hawai'i was formed by five volcanoes, but only three are considered active: Hualālai, Mauna Loa and Kīlauea. The latter are two of the world's most active volcanoes. A new sister volcano is Lō'ihi Seamount, an underwater active volcano about 20 miles (32 km) off the southeast coast of Hawai'i. L¯ō'ihi may be the next island in the Hawaiian chain. Currently, it is about 3,000 feet below sea level. If it continues to grow at the rate that the island of Hawai'i developed, 100,000 years will pass before L¯ō'ihi breaks the water surface.
