Iceland combines a midocean rift with a hotspot to similar effect.
Going back to what you said about Hotspots, I have included a new map in the above post. I have noted Hot Spots in several locations. I do have quite a bit of volcanic activity along plate edges. Is there every a situation where a particular plate is more vulnerable to have Hot Spots (such as plate I in the SW)? I could break it up into smaller plates, but it would be very difficult without producing some plates that simply couldn't exist. Any ideas?
