large stratovolcanoes (Vesuvius, Pinatubo) Peleean - collapse of ash columns --> pyroclastic flows (nuees ardentes), debris avalanche deposits or ignimbrites (Mt. Pelee, Martinique) Bandaian - lateral explosion --> cyclone-like (up to 150 km/hr) base surge deposits (Mount St. Helens) Volcano Morphology Volcano forms and processes are directly related to physical properties, compositions, and volumes (eruptive rates) of magmas, which in turn influence style of eruption.
