The type of volcano on Hawaii is a “Shield” volcano, and the volcano Fred explained is a “Composite” volcano.
A shield volcano has slowly flowing lava with no ash spouting out. Every volcano on Hawaii is this way. On the other hand, a composite volcano shoots out rock and ash, with a small amount of lava. A good example would be Mt. St. Helen’s. If a composite volcano were to erupt, it would not be on Hawaii.
