hot spot volcanoes are at the surface..they are a product of a volcanic plume (which is HUGE) under the lithosphere .. basically it heats up one spot on the plate for a really long time and eventually breaks through and starts piling up lava and pillow basalts till an island forms.. this takes MILLLIONS of years. the hawaiian islands are the perfect example of tracking a hotspot as the plate moves over it, although there are tons of other places around the world where you can see that.

I am not sure I understand your question. Hot spot volcanoes are on Earth's surface.
Hot spot volcanism is a result of a lithospheric plate moving over a mantle plume, very slowly. Examples of hot spot island chains are Hawaii, the Emperor Seamounts, and the Aleutians.
