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]
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]
Largest volcano in Europe by area, [18] and includes the peaks Plomb du Cantal and Puy Mary. Most recent eruption occurred 2-3 MYA. Puy de Sancy, in Auvergne-Rhône-Alpes. Both the tallest mountain in the Massif Central and volcano in France. [19] Most recent eruption occurred 200 thousand years ago. Monts Dore; Mont Ross; Gallieni Massif
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.

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 ...
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 ]
Most volcanoes of the Central Volcanic Zone are large composite volcanoes that can remain active for several million years, [12] but there are also conical stratovolcanoes with shorter lifespans. [11] In the Central Volcanic Zone, large explosive eruptions with Volcanic Explosivity Index of 6 and higher occur on average every 2,000 to 4,000 ...
Glacier Peak or Dakobed (known in the Sauk-Suiattle dialect of the Lushootseed language as "Tda-ko-buh-ba" or "Takobia" [5]) is the most isolated of the five major stratovolcanoes (composite volcanoes) of the Cascade Volcanic Arc in the U.S state of Washington.
