The Hawaiian Islands contain two main types of volcanoes: shield volcanoes, which have formed the bulk of the islands, and cinder cones, which are smaller in size. Several volcanoes fall into the subclass of cinder cone volcanoes known as tuff cone volcanoes. Keep Learning.
Hawaiian eruptions may occur along fissure vents, such as during the eruption of Mauna Loa Volcano in 1950, or at a central vent, such as during the 1959 eruption in KÄ«lauea Iki Crater, which created a lava fountain 580 meters (1,900 ft) high and formed a 38-meter cone named Pu Ê» u Pua Ê» i.ery little amounts of volcanic ash are produced. This type of eruption occurs most often at hotspot volcanoes such as KÄ«lauea and Iceland, though it can occur near subduction zones (e.g. Medicine Lake Volcano in California, United States) and rift zones.
