WebA narrow chain of explosive, rhyolite volcanoes forms on the surface of the moving plate. The areas of rhyolite underlying the Snake River Plain form discrete areas of volcanic activity, rather than one long ridge. This situation is analogous to that seen in the Pacific Ocean, where discrete islands form over the Hawaiian Hotspot. WebWhen two plates collide, one of the two plates subducts beneath the other and oceanic trenches are formed.

WebHow are Hotspot Volcanoes Formed? A hotspot forms when a plume of magma rises from the mantle and melts through whatever crust is above it. This new magma tries to reach the curface and creates a volcano. But when the tectonic plate shifts, new crust is suddenly above the hotspot, and a new volcano forms. This is how hotspot volcanoes form.
