WebVolcanoes form where the subducting oceanic plate gets hot. enough to “sweat” fluids and initiate melting. (Modified from Lillie, 2005.) Subduction zones produce volcanic arcs, … In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Examples include the Hawaii, Iceland, and Yellowstone hotspots. A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them.

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. How do islands form?

WebA volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. High heat and lower pressure at the base of the lithosphere (tectonic plate) facilitates melting of the rock. This melt, called magma, rises through cracks and erupts to form volcanoes.
