Evolution of Hawaiian volcanoes went through the rejuvenated stage, while its younger neighbors, East Molokai and West Maui, have evidently done so. It is currently unknown what stage of development the submerged volcano of Penguin Bank is in. In recent years research at other seamounts, for instance Jasper Seamount, has confirmed that the Hawaiian model applies to other seamounts as well.
