what are the main products of hawaiian eruptions
Typically they are effusive eruptions , with basaltic magmas of low viscosity , low content of gases , and high temperature at the vent . Very little amounts of volcanic ash are produced . This type of eruption occurs most often at hotspot volcanoes such as Kīlauea on Hawaii 's big island and in Iceland , though it can occur near subduction zones ( e.g. Medicine Lake Volcano in California , United States ) and rift zones .
