Not all volcanic islands are explosive. Many volcanic islands form at subduction zones, where an oceanic plate slides into the mantle. Such areas tend to produces viscous magma with water trapped in it. In an island setting, additional seawater often seeps into the volcano. As the magma approaches the surface and pressure drops, the water is explosively released as steam (other gasses are relased as well). This process stakes magma with it, forming ash and pumice.
