A hot spot for volcanic activity is an intensely hot area in the mantle below the Earth's crust. Hotspot volcanoes are considered to be different compared to volcanoes that occur from subduction zones. There are quite a lot of hotspots for volcanic activity.
Some of them are: Yellowstone hotspot, Louisville hotspot, Hawaii hotspot, Cameroon hotspot, Macdonald hotspot, Marion hotspot, Bouvet hotspot and Easter hotspot. These hotspots cut across all the continents on Earth.
In geology, the places known as hotspots are volcanic regions thought to be fed by the underlying mantle that is unusually hot compared with the surrounding mantle. A hotspot is an intensely hot area in the mantle below the earth's crust. The melted rock, known as magma often pushes through cracks in the crust to form volcanoes. Hotspot volcanism is unique because it does not occur at the boundaries of Earth's tectonic plates.
It happens at abnormally hot centers known as mantle plumes. Kauai is a hot spot. It is a Hawaiian island. The Yellowstone has a hotspot. The active Yellowstone caldera in Yellowstone National Park is a hotspot. The Louisville Sea Mount Chain is made up of over 80 Seamounts in the South Pacific Ocean. The seamounts originated from a single hotspot and had been slowly transported in a northwest direction by the Pacific Ocean.
