Mount Askja is primarily the result of volcanic activity associated with the Iceland hotspot, rather than subduction. This hotspot is responsible for the formation of Iceland and its volcanic features, as it creates magma that rises to the surface. The region's tectonic setting, located along the Mid-Atlantic Ridge, also contributes to its volcanic activity, but subduction is not a significant factor in Askja's formation.
Mount Etna is primarily the result of subduction processes. It is located at the intersection of the African and Eurasian tectonic plates, where the African plate is subducting beneath the Eurasian plate. This tectonic activity leads to the formation of magma that fuels the volcano. While hot spots can create volcanic activity, Etna's eruptions are mainly driven by the dynamics of plate tectonics.
No. Hot spots and subduction zones are two separate geogolgic settings in which volcanoes can form. Some hot spots may develop as a result of activity in a subduction zone, and continue activity after subduction has ended or move away.
Mount St. Helens is primarily related to a subduction zone, specifically the Cascadia Subduction Zone, where the Juan de Fuca Plate is being subducted beneath the North American Plate. This tectonic activity leads to volcanic eruptions and the formation of stratovolcanoes like Mount St. Helens. In contrast, hot spots are typically associated with volcanic activity in the middle of tectonic plates, such as the Hawaiian Islands, which is a different geological process.
Cone volcanoes which are likely to erupt explosively are found at subduction zones. Spreading zones (constructive plate boundaries) and hot spots produce quieter volcanoes because their lava is thinner. The ones at hot spots are shield volcanoes.
Cinder cone volcanoes have formed in all of the major land-based settings for volcanoes: subduction zones, hot spots, and rifts.

Mount Fuji was formed primarily by subduction. It is located at the convergent boundary between the Philippine Sea Plate and the Eurasian Plate, where the former is being subducted beneath the latter. This tectonic activity leads to volcanic eruptions, resulting in the formation of Mount Fuji as a stratovolcano. While hot spots can create volcanic activity, Mount Fuji's formation is predominantly attributed to the processes associated with subduction.

No, hotspot volcanoes do not occur along subduction zones. They occur when plates pass over mantle hot spots.
Most volcanoes that cannot be ascribed either to a subduction zone or to a seafloor spreading at mid-ocean ridges are attributed to hot spots.

There are two areas where volcanic mountains often form. They are subduction zones and hot spots.
Cinder cone volcanoes have formed in all of the major land-based settings for volcanoes: subduction zones, hot spots, and rifts.
