Volcanoes form at hot spots in the Earth's crust, at convergent plate boundaries where subduction of oceanic crust is occurring, and at divergent plate boundaries where gaps i â¦ n the crust are being infilled with rising magma.
Classic cone volcanoes form from ejected ash and lava when magma reaches the surface of a plate. The most likely places for a volcano to occur are near the 2 tectonic plates - Eurasian plate and the North American plate, in Ireland (Eyjafjallajokull).
