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.
A chain of volcanoes is created as the lithosphere moves over the source of magma. In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. [1] Examples include the Hawaii, Iceland, and Yellowstone hotspots.

The first, the main windward Hawaiian islands consist of the eight youngest and easternmost Hawaiian islands. This is the youngest part of the chain and includes volcanoes with ages ranging from 400,000 years [2] to 5.1 million years. [3] The island of Hawaiʻi comprises five volcanoes, of which two (Kilauea and Mauna Loa) are still active.
The Puhahonu volcano (Gardner) would be twice as big as Mauna Loa's based on that research. [5] [f] The Pūhāhonu and West Pūhāhonu volcanoes result from the Hawaii hotspot which is fed by the Hawaiian plume which had a major magmatic flux pulse at the time. [2] [c] A longer magmatic flux pulse produced the Hawaiian Islands.
A Hawaiian eruption is a type of volcanic eruption where lava flows from the vent in a relatively gentle, low level eruption; it is so named because it is characteristic of Hawaiian volcanoes. Typically they are effusive eruptions , with basaltic magmas of low viscosity , low content of gases, and high temperature at the vent.
La Perouse Pinnacle is a volcanic pinnacle approximately three miles (4.8 km) west southwest of East Island, Hawaii. [53] It is the oldest and most remote volcanic rock in the Hawaiian Islands. La Pèrouse Pinnacle stands 122 ft (37 m) tall. It is surrounded by coral reefs and a shorter, rocky islet about 5–10 feet (1.5–3.0 m) tall. Because ...
Mauna Kea (/ ˌ m ɔː n ə ˈ k eɪ ə, ˌ m aʊ n ə-/, [6] Hawaiian: [ˈmɐwnə ˈkɛjə]; abbreviation for Mauna a Wākea) [7] is a dormant shield volcano on the island of Hawaiʻi. [8] Its peak is 4,207.3 m (13,803 ft) above sea level, making it the highest point in Hawaii and the island with the second highest high point, behind New Guinea, the world's largest tropical island with ...
