Volcanic arcs are formed as a more dense oceanic plate collides with a less dense oceanic plate, subducts, and creates molten material which rises through the overriding plate, which in turn creates submarine volcanoes. The volcanoes may grow until they eventually breach the surface of the water, producing volcanic arc landmasses.
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
Island arcs form when oceanic lithosphere subducts under another oceanic plate or continental plate. The subduction process creates magma that rises to the surface, forming volcanic islands along the subduction zone. Over time, these volcanic islands can grow into a chain or arc of islands.
A series of volcanic islands that form along a plate boundary is called an island arc. This occurs when one tectonic plate subducts beneath another, leading to magma rising to the surface and forming a chain of volcanic islands. Examples of island arcs include the Japanese archipelago and the Aleutian Islands.

Volcanic island arcs are likely to result from convergent boundaries where an oceanic plate subducts beneath another oceanic plate or a continental plate. The subducted plate can melt, causing magma to rise and form a series of volcanic islands above the subduction zone.

Volcanic islands are often found at convergent plate boundaries where one tectonic plate is subducted beneath another. This subduction process can lead to the formation of volcanic arcs, such as the islands of Japan, Indonesia, and the Aleutian Islands.

Santorini volcano was formed by the conversion of the African plate and the Aegean Sea Plate. As subduction occurred, some magma burned to the surface and create volcanic islands called island arcs. Santorini is one of those volcanic islands.
Volcanic island arcs are likely to result from convergent boundaries where an oceanic plate subducts beneath another oceanic plate or a continental plate. The subducted plate can melt, causing magma to rise and form a series of volcanic islands above the subduction zone.
A convergent plate boundary where two tectonic plates of oceanic crust meet, and the denser of the two subducts below the other. The water content of the subducting crust lowers the melting point of the rocks around it and a pool of lighter molten rock rises to form characteristic volcanic island arcs such as the Aleutian Islands in Alaska.
Ocean trenches, volcanic arcs, and island arcs are examples of geologic features on the ocean floor formed by crustal plates moving together. Subduction zones are common in these areas, where one plate is forced beneath another, creating deep ocean trenches and leading to volcanic activity along the plate boundaries. Island arcs can also form as a result of subduction, with chains of volcanic islands aligning parallel to the trenches.
Volcanic arcs and oceanic trenches commonly form at subduction zones.
