As a result, they are less explosive than subduction zone volcanoes, in which water is trapped under the overriding plate. Where hotspots occur in continental regions, basaltic magma rises through the continental crust, which melts to form rhyolites. WebContinental Hotspot.

"WebJan 2, 2024 · How do hotspot volcanoes form? Hotspots occur when one of the Earth’s plates moves over an unusually hot part of the Earth’s mantle. These hot areas are usually relatively stationary and result in large amounts of magma rising up, piercing a hole in the plate to form a volcano. As the plates move, a series of volcanoes can form.
