At subduction zones due to the occurrence of very large thrust faults.
The most violent volcanic eruptions are found in destructive/convergent plate boundaries. 80% of the world's active volcanoes are found occur along destructive boundaries. Acid-lava and composite volcanoes also cause the most violent eruptions as the lava is viscous and the opening of the volcano is sometimes blocked by hardened lava, causing a huge massive explosion during the eruption.
Typically, Plinian eruptions are more destructive than Vulcanian eruptions. Plinian eruptions produce massive volcanic columns and pyroclastic flows, which can travel long distances and cause widespread devastation. In contrast, Vulcanian eruptions are characterized by short, explosive bursts of ash and gas, which are generally less powerful and have a more limited impact.
The most destructive to least destructive kinds of eruptions are as follows:PlinianPeleanStrombolianHawaiianMost to leastPlinian, Pelean, Vulcanian, Fissure
Indonesia has the most volcanic eruptions per year, as it lies on the Pacific Ring of Fire, a region prone to volcanic activity due to tectonic plate movements. Indonesia is home to numerous active volcanoes, making it a hotspot for volcanic eruptions.
Undersea earthquakes or volcanic eruptions.
Hawaiian eruptions are the least severe. It is a 0 on the Volcanic Explosivity Index VEI scale.Strombolian eruptions are relatively mildly explosive 1-2 on the VEI scale.Vulcanian eruptions are 2-3 on the VEI scale.Peléan eruptions are 4-5 on the VEI scale.Plinian eruptions are the most destructive. They are from 6-8 on the VEI scale.http://ete.cet.edu/gcc/?/volcanoes_explosivity/

When eruption types are arranged from most destructive to least, it is in descending order.
Most common would be a fissure eruption of basaltic magma.

Volcanoes are located throughout most of the world. The most active volcanoes are found on the so-called "ring of fire" in Pacific Ocean. Indonesia has several volcanoes including Krakatoa. Hawaii's Kilauea produces the most lava of all active volcanoes in the world. North America has Mt. St. Helens and Mt. Rainier in Washington, USA. Mexico has several including Parícutin and Nevado de Toluca. Europe has Mt. Etna. Generally, volcanoes are located near tectonic plates that are converging or diverging.
