  1. Stratovolcanoes are the most familiar-looking volcanoes. They're usually created in subduction zones (when one tectonic plate pushes up another), and look like mountains. They have steep, symmetrical sides with small summit craters. This combination of steep sides and a small crater leads to the most violent type of eruptions. They spew out a lot of hard volcanic material, as well as ash and lava. The volume and force of all these materials are what help create the mountain-like edifice around the volcano's vent. Stratovolcano eruptions are often violent, but they also are infrequent, usually coming hundreds of years apart.
