A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice and ash.Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas.

Stratovolcanoes form when a conduit grows out from a pocket of magma and eventually reaches the surface. Over millions of years and countless eruptions, the magma and ash cool and settle, forming the large, summit-like volcano. Stratovolcanoes grow larger than any of the other types of volcano and some reach more than a mile in height.
A stratovolcano is a conical-shaped volcano composed of steeply-dipping layers of lava, hardened ash, and other material erupted from the main volcanic vent. Stratovolcanoes are also commonly ...
Left: This is a schematic diagram of a strato volcano, intended to illustrate the different layers of different materials that comprise them. The purple colors are meant to represent ash layers, either the products of fall-out from big eruption clouds or the products of pyroclastic flows. Notice that these ash layers tend to be thin but widespread.
A stratovolcano is a tall, conical volcano composed of one layer of hardened lava, tephra, and volcanic ash. These volcanoes are characterized by a steep profile and periodic, explosive eruptions.
