subduction boundary eruption
Eruptions that occur where two lithospheric plates come together are typically explosive in nature due to the subduction of one plate beneath the other. This subduction creates magma chambers that can lead to violent eruptions, such as those seen in volcanic arcs like the Ring of Fire. The resulting volcanic activity is often associated with earthquakes and the formation of mountain ranges.
Volcanic eruptions at plate boundaries occur when one plate subducts beneath the other, allowing magma to rise and erupt on the surface. This often leads to explosive eruptions due to the pressure buildup of gases in the magma. Additionally, the melting of the subducted plate can create a magma chamber that fuels volcanic activity.

Volcanic eruptions occur only in certain places and do not occur randomly. That's because the Earth's outermost shell -- the lithosphere -- is broken into a series of slabs known as lithospheric ortectonic plates. These plates are rigid, but they float on the hotter, softer layer in the Earth's mantle. There are 16 major plates. As the plates move about, they spread apart, collide, or slide past each other. Volcanoes occur most frequently at plate boundaries.
Mid-ocean ridges and deep sea trenches (with their associated volcanos). Also in limited areas strike-slip fault systems (e.g. California), continental collision zones (e.g. India & Asia), etc.
Earthquakes occur near faults and near the edges of plates in the earth's crust. Volcanic eruptions occur wherever a volcano is. Volcanic eruptions can occur when magma from below Earth's surface seeps through a weak spot in the crust. Volcanoes occur along plate boundaries, along the edges of plates, so this is where volcanoes occur also.

The theory of plate tectonics helps to explain how earthquakes and volcanic eruptions occur.
Stratovolcanoes are usually found along convergent plate boundaries where an ocean plate is pushed under another ocean plate or a continental plate (subduction zone). If you are referring to convergent boundaries in which neither plate is subducted but both are pushed up to form mountains, then my answer would have to be that it is very rare for a volcano to form at this type of boundary.
Most common would be a fissure eruption of basaltic magma.
Lithospheric plates made up of the upper mantle and crust float on the soft, flowing aesthenosphereand are moved around by the flow of the aesthenosphere caused by convection from the core.
