Hawaii is a chain of volcanic islands. Volcanic activity is what formed the islands. Under the Pacific ocean where Hawaii is located is what is known as a volcanic hot spot. â¦ Magma erupted from under sea volcanoes as the tectonic plate moved over the hotspot forming sea mounts (islands under the sea).When these sea mounts broke the surface they became the Hawaiian islands.nder the Pacific ocean where Hawaii is located is what is known as a volcanic hot spot. â¦ Magma erupted from under sea volcanoes as the tectonic plate moved over the hotspot forming sea mounts (islands under the sea).
