There are other hot spot volcanoes. Yellowstone and Iceland are two you might be familiar with. Yellowstone differs in that the magma must rise through a continent. As it does it becomes more silica rich and eruptions are infrequent, large, and very violent. In Iceland the composition of the magma does not change but volcanism is more complicated because Iceland is also on the mid-Atlantic ridge, a spreading plate boundary.
Eruptions are similar to Hawaii in style buy less frequent.
Stratovolcanoes are associated with subduction zones where oceanic plates are pushed beneath lighter plates, usually plates with continental crust.
