Final answer:

Volcanic island arcs are associated with convergent oceanic-oceanic plate boundaries, where one oceanic plate subducts under another causing magma to rise and form an arc of volcanoes.

Step-by-step explanation:

Volcanic island arcs are typically associated with convergent oceanic-oceanic plate boundaries. This occurs when two oceanic plates converge, and one plate, being denser, subducts beneath the other into the mantle where it begins to melt. As a result of this process, magma rises to create a series of volcanoes in an arc shape on the overriding plate, leading to the formation of an island arc. These island arcs are a clear indicator of the intense geological activity that occurs at convergent boundaries where subduction takes place.
