A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers 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]
Mount Katmai (Russian: Катмай) is a large active stratovolcano (composite volcano) on the Alaska Peninsula in southern Alaska, located within Katmai National Park and Preserve. It is about 6.3 miles (10 km) in diameter with a central lake-filled caldera about two by three miles (3.2 by 4.8 km) in size, formed during the Novarupta eruption ...

The catastrophic June 1991 eruption, which formed a caldera, later filled by a crater lake, had global environmental effects. Mount Bulusan in Sorsogon; Mount Kanlaon and Mount Talinis in Negros
The typical stratocone is an andesitic to dacitic volcano that is associated with subduction zones. They are also known as either stratified volcano, composite cone, bedded volcano, cone of mixed type or Vesuvian-type volcano. [1] [2]

They are also known as composite volcanoes because they are created from multiple structures during different kinds of eruptions; the main conduit bringing magma to the surface branches into multiple secondary conduits and occasional laccoliths or sills, the branching conduits may form parasitic cones on the flanks of the main cone.

Most sources, including Wikipedia, emphasise that shield volcanoes and composite volcanoes have different features and are not the same type of volcano. Confusingly, "composite volcanoes" are usually assumed to be synonymous with stratovolcanoes; in Wikipedia "composite volcano" redirects to the stratovolcano article. This would probably raise ...
A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. [1] They may form due to changes in eruptive habit or in the location of the principal vent area on a particular volcano. [ 2 ]
