Of the total area of Japan, which is about … Hawaii, Hawaiian Hawai‘i, volcanic island, Hawaii, U.S.It lies southeast of Maui island and constitutes Hawaii county. If the hot-spot theory is correct, the next volcano in the Hawaiian chain should form east or south of the Island of Hawai'i. The Hawaiian Islands formed primarily as a result of volcanic activity. For example, the Hawaiian Islands, which are entirely of volcanic origin, have formed in the middle of the Pacific Ocean more than 3,200 km from the nearest plate boundary.

The islands are formed over a stationary mantle plume and then are carried to the northwest on the Pacific Plate. Lesson at a Glance ... • The Hawaiian archipelago was formed by a stationary hot spot deep in the Earth’s mantle, away from plate boundaries. Hawaii provides an exquisite natural laboratory for studying soil development. The Hawaiian Island chain is a collection of volcanic islands in the Pacific Ocean that have formed over a hotspot in the centre of a tectonic plate, rather than at a plate boundary (where volcanoes commonly form). Under the Hawaiian Islands, there is a volcanic “hot spot,” a hole in the Earth’s crust that allows lava to surface and layer.Over millions of years, these layers form mountains of volcanic rock that eventually break the surface of the Pacific Ocean, forming islands.As the Pacific Plate very slowly moves across the hot spot, new islands are formed.
