What is a Stratovolcano?

• The stratovolcano is a tall, steep, and cone-shaped type of volcano. 
• Unlike flat-shield volcanoes, they have higher peaks. At their peak, stratovolcanoes usually have a small crater. The crater may be filled with water or ice, or it may contain a volcanic dome during a period of relative inactivity.
• Stratovolcanoes comprise the largest percentage (~60%) of the Earth's volcanoes, and most are characterised by eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt. 
• These more viscous lavas allow gas pressures to build up to high levels. Therefore, these volcanoes often suffer explosive eruptions.
• They are usually half lava and half pyroclastic material, and the layering of these products gives them their other common name of composite volcanoes.
