What is a stratovolcano?
- A stratovolcano is a type of volcano that is tall, steep, and cone-shaped.
- They have taller peaks than flat-shield volcanoes. Stratovolcanoes typically feature a tiny crater at their summit.
- During relative inactivity, the crater may be filled with water or ice, or it may contain a volcanic dome.
- Stratovolcanoes account for most of the Earth's volcanoes (60%) and are typified by eruptions of andesite and dacite, which are colder and denser than basalt.
- These more viscous lavas allow for large gas pressures to develop up. As a result, these volcanoes frequently have violent eruptions.
- They are frequently half lava and half pyroclastic debris, and the layering of these products lends them their other popular name of composite volcanoes.
