three tectonic settings where volcanoes commonly occur
As previously mentioned volcanoes occur at weaknesses in the Earths surface, these are in one of three tectonic settings: subduction volcanoes, rift volcanoes and hot spot volcanoes.ift volcanoes occur where tectonic plates diverge, often on the ocean floor. These are generally less explosive. Hot spot volcanoes occur in the middle of plate boundaries where magma exits from weaknesses in the earth's surface. The Hawaiian Islands are an example of hot spot volcanoes.
