Composite volcanoes most often form near subduction zones.
Lava high in silica (granitic lava) tends to be thick and viscous, so the volcano is likely to be composite rather than shield.
A volcano is most likely to form at a convergent plate boundary, where two tectonic plates collide, forcing one plate to subduct beneath the other. The subducted plate melts and rises to the surface, forming a volcano.
Mount Mayon, the Phillipines, is a stratovolcano, or a composite volcano. The lava erupted has a high silica content and high viscosity, and is mainly andesitic. Mount Mayon is categorised as active, and is viewed as a 'perfect volcano' due to the symmetry of sides.
A shield volcano is most likely to form fluid lava because it is characterized by gentle sloping sides and eruptions of low-viscosity magma. This type of volcano typically produces basaltic lava that flows easily and spreads over large distances.
Pelean eruptions are most commonly seen at stratovolcanoes, which can also be called composite volcanoes.

This is a stratovolcano, also known as a composite volcano.
Composite volcanoes are highly variable in what they erupt. Most often, eruptions will release clouds of ash, pumice, and rock fragments. In some cases they fountain or extrude lava.
A caldera is a large depression in a volcano. Most calderas form in one of two ways: by collapse of the top of a composite volcano after the magma chamber is drained.
The type of volcano appears most in the news are composite and cinder cone
Composite or Strato Volcanoes.
Composite volcanoes most often have a gray color and may be capped with snow.

the composite, and it can basically self distruct too!
