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.
Most hotspot volcanoes are basaltic (e.g., Hawaii, Tahiti). As a result, they are less explosive than subduction zone volcanoes, in which water is trapped under the overriding plate. Where hotspots occur in continental regions , basaltic magma rises through the continental crust, which melts to form rhyolites .

(Ma = million years) Map of the Hawaiian Islands and some of the Emperor seamounts showing progression in selected erupted lava ages along the chain (Ma = million years) The Hawaiian–Emperor seamount chain is a series of volcanoes and seamounts extending about 6,200 km (3,900 mi) across the Pacific Ocean.

The Hawaiian Volcano Observatory (HVO) is an agency of the United States Geological Survey (USGS) and one of five volcano observatories operating under the USGS Volcano Hazards Program. Based in Hilo, Hawaii , the observatory monitors six Hawaiian volcanoes: Kīlauea , Mauna Loa , Kamaʻehuakanaloa (formerly Lōʻihi), Hualālai , Mauna Kea ...
First prepared in 1974 by Donal Mullineaux and Donald Peterson of the USGS and revised in 1992 for the Island of Hawaiʻi, [1] the maps outline the qualitative hazard posed by lava flows based on the history of lava flow activity on each of the five volcanoes that form the Island of Hawaiʻi and Haleakalā volcano on the island of Maui.
