The next volcanic island would most likely form to the southeast of the existing islands, following the direction of the crustal plate movement over the magma source in the mantle. As the plate continues to shift, it will expose new areas above the magma hotspot, resulting in volcanic activity and the formation of an island in that region.

Yes, Antigua is not a volcanic island. It is a low-lying island formed mainly from limestone and coral reefs. There are no active volcanoes on the island.
Hawaii is a volcanic island, formed by volcanic activity millions of years ago. It is part of a volcanic island chain in the Pacific Ocean.
An example of a geological feature that is not a small crustal fragment is an oceanic island arc, such as the Aleutian Islands. Unlike small crustal fragments, which are typically pieces of continental crust, oceanic island arcs are formed from volcanic activity at tectonic plate boundaries and do not collide with continental landmasses to create mountainous topography. Instead, they are primarily associated with subduction zones and exhibit different geological characteristics.
Montserrat is a volcanic island because it was formed by the rising magma from the Earth's mantle through a weak spot in the Earth's crust, leading to the accumulation of layers of volcanic rock over time. This volcanic activity has resulted in the island's rugged topography and the presence of volcanic features such as lava domes and pyroclastic flows.
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 islands are formed by volcanoes and are therefore composed of volcanic rock.

The island in Crater, called Wizard Island was formed by small volcanic eruptions that occurred after the Crater Lake caldera formed but before the volcano went extinct.
Yes, Hispaniola island was formed by volcanic activity in the past, but it is not currently an active volcanic area. The island is located in the Caribbean and is shared by the countries of Haiti and the Dominican Republic.
A newly formed land consisting of an arc-shaped island chain is called a volcanic island arc. These volcanic islands are typically formed due to the convergence of tectonic plates where one plate subducts beneath another, leading to magma rising to the surface and creating a chain of volcanic islands.
