Many volcanic islands are a product of plate boundaries, but some, such as the Hawaiian islands, form over hot spots away from plate boundaries.
they are not as violent because the plates are sliding away from each other and it is a much smoother process
It is because volcanoes form by two tectonic plates which when both collide and they form volcanoes which a magma rock forms when it explodes.
What type of boundaries cause volcanoes? Divergent and transform fault boundaries cause volcanoes because they separate. Convergent boundaries cause earthquakes because they collide with other plates.
When plates are different densitys and collide to make volcanoes.
convergence plate boundary, where tectonic plates move towards each other and collide, leading to subduction zones which are highly constructive regions of volcanoes. Volcanoes also form at divergent plate boundaries. A good example being the numerous Icelandic volcanoes which have formed over he Mid Atlantic Ridge.

HaitiJapan has quite a lot as it is on the boundary of several tectonic plates.
The type of boundary associated with Icelandic volcanoes is the constructive plate boundary, where two plates slowly move apart and magma seeps up through the gap.
Hotspot volcanoes form over a fixed hotspot in the mantle, resulting in a chain of volcanoes as the tectonic plate moves over it, like the Hawaiian Islands. Volcanoes at plate boundaries are formed by the interaction of tectonic plates, where one plate is forced under another (subduction) or plates move apart (divergence), creating volcanic activity along the boundary, like the Ring of Fire.
A convergent boundary is formed when plates collide. At this type of boundary, the denser plate sinks beneath the less dense plate in a process known as subduction. This collision often results in the formation of mountain ranges, volcanoes, and deep ocean trenches.
Because it is located on the boundary of two tectonic plates the Filipino plate and the Pacific plate. Where two plates meet is where earthquakes, volcanoes etc occur. click on 'related links' below to see a picture of tectonic plates.
