The islands are exposed peaks of a great undersea mountain range known as the Hawaiian–Emperor seamount chain, formed by volcanic activity over the Hawaiian hotspot. The islands are about 1,860 miles (3,000 km) from the nearest continent and are part of the Polynesia subregion of Oceania .
After failing to find any passage, he decided to use the Hawaiian Islands as a base to over-winter and resupply before a second attempt the next season. His two ships first encountered the coast of Maui in November 1778, and eventually anchored in Kealakekua Bay on the west coast of Hawaii Island in mid January. Initially, the reception of the ...
The Hawaiian islands were formed by volcanic activity initiated at an undersea magma source called the Hawaiʻi hotspot. The process is continuing to build islands; the tectonic plate beneath much of the Pacific Ocean continually moves northwest and the hotspot remains stationary, slowly creating new volcanoes. Because of the hotspot's location ...
The Hawaiian–Emperor seamount chain is a mostly undersea mountain range in the Pacific Ocean that reaches above sea level in Hawaii.It is composed of the Hawaiian ridge, consisting of the islands of the Hawaiian chain northwest to Kure Atoll, and the Emperor Seamounts: together they form a vast underwater mountain region of islands and intervening seamounts, atolls, shallows, banks and reefs ...
The Hawaiʻi hotspot is a volcanic hotspot located near the namesake Hawaiian Islands, in the northern Pacific Ocean.One of the best known and intensively studied hotspots in the world, [1] [2] the Hawaii plume is responsible for the creation of the Hawaiian–Emperor seamount chain, a 6,200-kilometer (3,900 mi) mostly undersea volcanic mountain range.
18th-century Hawaiian helmet and cloak, signs of royalty. Ancient Hawaiʻi was a caste society developed from ancestral Polynesians. In The overthrow of the kapu system in Hawaii, Stephenie Seto Levin describes the main classes: [27] Aliʻi. This class consisted of the high and lesser chiefs of the realms.
The Hawaiian–Emperor seamount chain. The two straight sections, the Emperor and Hawaiian strands, are separated by a large L-shaped bend at the Northwestern Hawaiian islands.

As shield volcanoes, they are built by accumulated lava flows, growing a few meters or feet at a time to form a broad and gently sloping shape. [2] Hawaiian islands undergo a systematic pattern of submarine and subaerial growth that is followed by erosion. An island's stage of development reflects its distance from the Hawaii hotspot.
