Figure 1âRising Lava and a String of Pearls. The Hawaiian Islands are the last in a string of volcanic islands that arose as the Pacific Plate moved over a âhot spotâ in the crust. At the end of the Flood, eruptions began to produce dozens of islands stretching over 3,600 miles (5,800 km). The hot spot currently sits under Hawaiiâs Big Island.
Island arcs are volcanic islands that form parallel to ocean trenches in subduction zones. The Pacific Ring of Fire is home to many of these groups of islands. Volcanoes that form above hot spots like the Hawaiian islands are not volcanic arcs.Volcanic island eruption, USGS. Two oceanic plates converge. Islands form an arc when two oceanic plates converge creating a row of islands above the overriding plate.The older plate, which is heavier and denser, is forced beneath the lighter plate.he melting plate feeds magma chambers that supply volcanic islands that form an arc when the molten rock erupts onto the ocean floor of the overriding plate. Mariana Islands. Deep ocean trenches form between the converging plates.
