Azores hotspot Azores hotspot The Azores hotspot is a volcanic hotspot located at the Azores in the Northern Atlantic Ocean. A volcanic hotspot is defined as an area of high volcanic activity, a long term source of volcanism.

The Azores hotspot also differs from usual hotspots like Hawaii due the fact that it has interactions with the Mid-Atlantic Ridge, which lies just west of the hotspot. The centre of the hotspot
