Hotspot (geology)
volcanic region / From Wikipedia, the free encyclopedia
In geology, a hotspot or hot spot is a portion of the Earth's surface which is volcanic. This may be caused by a rising mantle plume or some other cause.[2] 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. The Earth's plates may move along, creating a new volcano above the hotspot while moving the older volcanoes away. This creates a chain of volcanoes, such as in Hawaii.
