The Hawaiian Islands contain two main types of volcanoes: shield volcanoes, which have formed the bulk of the islands, and cinder cones, which are smaller in size. Several volcanoes fall into the subclass of cinder cone volcanoes known as tuff cone volcanoes. Keep Learning.
These other types of volcanoes (common outside of Hawaii) are typically steeper sided. The Hawaiian volcanoes were produced by the Hawaiian hot spot, which is presently under the Big Island of Hawaii. The image below shows the islands of the Hawaiian chain and the intervening shallows, banks and reefs along a line from southeast to northwest.
