Where is a hotspot on a volcano found?

Answer 1

A volcano hotspot is a region on the Earth's surface that has experienced volcanism for a long time. A good example of this is the Hawaiian Islands. Each of the islands in the long chain were created by the same volcano hot spot. The volcano built up an island that extended above the surface of the ocean, and then plate tectonics carried the island away, creating an extinct volcano. But there's always a new volcano being created by the same hot spot.

There are dozens of volcano hot spots around the world, with the Hawaiian Island chain just being the most well known. Others include the Azores hotspot, the Canary hotspot and the East Australia.

Answer 2

A hotspot on a volcano is typically found where magma rises from deep within the Earth's mantle, creating a weak point in the Earth's crust that allows lava to reach the surface. This usually occurs at the summit or along fissures on the flanks of the volcano.

Answer 3

A hot spots is not something you find on a volcano. Some volcanoes form on hot spots. A hot spot is an area where mantle material that is hotter than the surrounding material rises up and gathers beneathe the crust. Ome of this melts into magma and rises to the surface to form volcanoes. About 10% of volcanoes are the result of hot spots. The rest are formed at plate boundaries. The most well-known hot spot volcanoes are the Hawaiian volcanoes.

Answer 4

In geological terms, volcanic hotspots are volcanic regions below which volcanism occurs because of a rising mantle that is hotter than the surrounding mantle. The rising mantle is as a result of lava activity from underneath and may even erupt from time to time. The position of tectonic plate boundaries in volcanic hotspots does not in any way affect the hot mantles. In many cases, hotspots remain constant while tectonic plates move further away thus leaving a trail of volcanoes, the oldest being the furthest away from its original location. There are different suggestions as to the origin and composition of volcanic hotspots. The majority of volcanic hotspots consist of extrusive igneous rock (basalt) that have formed over the years due to rapid cooling lava that is exposed at the Earth’s surface. This non-violent-eruption formation makes the rocks cool quickly and form crystals. For volcanic hotspots that are within the continental regions, magma rises onto the continental crust and forms rhyolites which have high chances of forming violent eruptions. If and when rhyolites completely erupt, the next eruptions are usually of basaltic magma that rises through the cracks in the lithosphere to the continental crust. However, hotspots should never be confused with island volcanoes because they have different origins from island arc volcanoes.

Answer 5

Hot spot volcanoes are areas where magma from deep within the mantle melts through the crust above it.

Answer 6

Hawaii is one of them. Hawaii is one of the major hotspots, in fact Hawaii itself and the islands connected with it are all hotspot volcanoes. hope this helps

Answer 7

A volcano hot spot is where material deep inside the mantle rises and cools making magma

Answer 8

a hotspot is found above the magma plumes
