Island Arcs are formed on the opposing edge of a subducted slab. For each case, there is an associated subducting slab and a trench. The trenches for these island arcs can barely be made out in this map.2.) The second way in which islands are formed is via plumes or hot spots in the lithosphere. The Hawaiian Islands are an example of this type of island formation.In this case, there is no associated subducting slab.sland Arcs are formed on the opposing edge of a subducted slab.

Kilauea volcano Kilauea is one of the most active volcanoes on our planet. The volcano began the longest rift-zone eruption in historic times on January 3, 1983. Lava fountains formed in the rift zone about ten miles below the summit caldera.Powerful eruptions threw molten rock high in the air building a cinder cone.ig Island volcanoes.
