Greece has one of the most well-known volcanic arcs worldwide, which was created by the sinking of the African lithosphere (Oceania) under the Eurasiatic plate (mainland). The Greek volcanic arc with its especially intense volcanic activity in the past is responsible for the formation of quite a few of the more impressive and many times eerie volcanic landscapes that we come across in many regions throughout Greece.
