Volcanic Landforms
This site describes volcanic landscapes, which contain diverse landforms such as edifices, calderas, and lava domes. The three main edifices are scoria cones, shield volcanoes, and stratovolcanoes. A chart shows the outline of each along with its composition and eruption type. The calderas described include Crater-Lake type calderas associated with the collapse of stratovolcanoes, basaltic calderas associated with the summit collapse of shield volcanoes, and resurgent calderas which lack an association with a single centralized vent. The creation of lava domes is discussed and the morphology of Mt. St. Helens is illustrated.
