Stratovolcano also known as composite cones, are the most picturesque and the most deadly of the volcano types. Their lower slopes are gentle, but they rise steeply near the summit to produce an overall morphology that is concave in an upward direction.

Stratovolcanoes, also known as composite volcanoes, include some of the best-known – and most dangerous – volcanoes on Earth. Stratovolcano eruptions tend to alternate between "quiet" lava flows and much more explosive blasts that send volcanic rock down the slope of the volcano.
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.
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 ...
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.
A stratovolcano is a tall volcano shaped like a cone, formed by various layers of materials such as volcanic ash, hardened lava, pumice, and tephra. Stratovolcanoes are steep and have periodic explosive and effusive eruptions, although some have calderas, which are collapsed craters. The highly ...

Stratovolcano . Strato Volcanoes comprise the largest percentage (~60%) of the Earth's individual volcanoes and most are characterized 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 (they are effective "plugs" in the plumbing ...
Composite Volcano. A composite volcano forms in subduction zones when a crustal plate is forced into the mantle and begins to melt. Andesite, dacite and rhyolite lavas are the primary types of lava that form these volcanoes. Eruptions on the volcanoes often alternate between tephra and lava flows.
