There is an ongoing discussion about whether the hotspot is caused by a deep mantle plume or originates at a much shallower depth. [3] Recently, seismic tomography studies have found seismic wave speed anomalies under Iceland, consistent with a hot conduit 100 km (62 mi) across that extends to the lower mantle.
Map showing approximate location of many current hotspots and the relationship to current tectonic plates and their boundaries and movement vectors The origins of the concept of hotspots lie in the work of J. Tuzo Wilson , who postulated in 1963 that the formation of the Hawaiian Islands resulted from the slow movement of a tectonic plate ...

Bonchurch Landslips is a 28.2-hectare (70-acre) site of special scientific interest which is located north-east of Ventnor, Isle of Wight.A wooded coastal landslip zone, the site was notified in 1977 for both its biological and geological features.
The Tristan hotspot is marked 42 on this map of hotspots. The Tristan hotspot is a volcanic hotspot which is responsible for the volcanic activity which forms the volcanoes in the southern Atlantic Ocean. It is thought to have formed the island of Tristan da Cunha and the Walvis Ridge on the African Plate. [1]

The Azores hotspot is marked 1 on map. The Azores hotspot is a volcanic hotspot in the Northern Atlantic Ocean. The Azores is relatively young and is associated with a bathymetric swell, a gravity anomaly and ocean island basalt geochemistry. [1] The Azores hotspot lies just east of the Mid-Atlantic Ridge [2]
