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]
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
A shield volcano is a type of volcano named for its low profile, resembling a shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity ) lava , which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano .
Unlike monogenetic volcanoes, polygenetic volcanoes reach massive sizes, such as Mauna Loa, which is the world's largest active volcano. Polygenetic volcanoes include stratovolcanoes , complex volcanoes , somma volcanoes , shield volcanoes and calderas .
The Cascade Arc includes nearly 20 major volcanoes, among a total of over 4,000 separate volcanic vents including numerous stratovolcanoes, shield volcanoes, lava domes, and cinder cones, along with a few isolated examples of rarer volcanic forms such as tuyas. Volcanism in the arc began about 37 million years ago; however, most of the present ...

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 ]
This list of shield volcanoes includes active, dormant and extinct shield volcanoes. Shield volcanoes are one of the three types [ specify ] of volcanoes. They have a short cone shape, and have basaltic lava which means the lava has low viscosity (viscosity is a measure of the ability for a liquid to flow)
