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 …

Hotspots may be far from tectonic plate boundaries.. A volcanic hotspot is where magma pushes up from deep in the Earth's crust or mantle and creates a volcano.
