Stratovolcano
Type of conical volcano composed of layers of lava and tephra
A stratovolcano, also known as a composite volcano, is a typically conicalvolcano built up by many alternating layers (strata) of hardened lava and tephra.[1] Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions.[2] Some have collapsed summit craters called calderas.[3] The lava flowing from stratovolcanoes typically cools and solidifies before spreading far, due to high viscosity.
The magma forming this lava is often felsic, having high to intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less viscous maficmagma.[4] Extensive felsic lava flows are uncommon, but can travel as far as 8 km (5 mi).[5]
The term composite volcano is used because strata are usually mixed and uneven instead of neat layers.[6] They are among the most common types of volcanoes;[7] more than 700 stratovolcanoes have erupted lava
