According to the Hot-Spot hypothesis to explain the origin of some volcanic islands:
O There is a moving volcanic plume in the upper part of the mantle that moves faster than the actual tectonic plate. This plume generates volcanic activity
O There is a static volcanic plume in the upper part of the mantle that generates volcanic activity
O There are long cracks in the mantle that create these islands
O The volcanic activity of all of the intraplate volcanic islands can be explained with this hypothesis
