The Hawaiian Islands are volcanic islands, thus islands that have been created by volcanic activity. Unlike most of the volcanic islands, or most of the volcanoes, they are not related to any type of volcanism asociated with plate boundary. These islands are in fact associated with intraplate volcanism.
The intraplate volcanism, unlike the other volcanisms, appears inside the plate, not on the boundary of it. The other, more common name, used for this volcanism is hot spot volcanism. This type of volcanic activity appears on places where there's a hot spot, so even though the plate is on top of it, it manages to penetrate through it, and create volcanoes on the surface.
