Volcanoes on continents can develop at path convergent and divergent boundaries. They can occur where an oceanic plate subducts under a continental plate, producing a volcanic arc such as in the Cascade Range. Volcanoes can also occur in areas of rifting, such as Africa's Great Rift Valley, a developing divergent boundary. Where two oceanic plates converge volcanoes can develop underwater and eventually form volcanic islands.
Volcanoes can also develop away from a plate boundary over a hot spot.
Vesuvius is associated with a convergent boundary between the African Plate and the Eurasian Plate.
transform boundary
Virtually all of the world's volcanoes are located at the boundaries between tectonic plates. It is most common to find volcanoes where an oceanic plate collides with a continental plate. It is the boundary between the Pacific Plate and the continental plates around it that is called the "ring of fire" because so many volcanoes are formed at this boundary. In the collision the denser oceanic plate will be forced underneath of the continental plate. This is called 'subduction', and it usually occurs in destructive plate boundaries. Volcanoes are then formed, when the oceanic plate melts and the molten rock rises, being squeezed up by the forces of the mass above.
The boundary between the Gorda plate and the North American Plate is a transform boundary. Transform boundaries that lie at near land are the most destructive, which is the case in Southern California, which is close to this plate boundary.
Convergent boundaries form mountains and volcanoes.
No. A volcano is not a plate boundary. Most volcanoes on land are associated with convergent boundaries, but many are associated with divergent boundaries and others with hot spots.
Vesuvius is associated with a convergent boundary between the African Plate and the Eurasian Plate.
The Himalayas are found at a convergent plate boundary also known as a subduction zone where one plate slips under the other driving the land mass up.

A constructive plate boundary, as it pushes land upwards (which formed the mountains)
The type of boundary that the Andes mountains are, in South America, is a convergent plate boundary. This was formed from the collision of the South American plate boundary and the Nazca plate.

Tectonic plate Boundaries, both Continental, can press against each other until the land is lifted and folded over itself. This is often called a Collisional Plate Boundary and can cause earthquakes, however not volcanoes.
In almost all cases the oceanic plate subducts under the continental plate, creating a trench on the seafloor off the coast and an arch of volcanoes inland on the continent. The lava of these volcanoes has a high water content, making their eruptions very explosive.
