Lava flowing is one thing,
a volcano blowing its' top off quite another.
The Hawaiian volcanoes are shield volcanoes; quite different from Krakatoa, Thera, Martinique, or Mt. St. Helen. Vesuvius and Mt. St. Helen are inland, which refutes the older notion that such pyroclastic flows result from steam expanding when sea water entered the magma chamber. Hawaiian lava is viscous and slow flowing; the eruptions of Vesuvius and Mt. St. Helen were mainly ash and lapilli. Quite a different dynamic.
