A student asked me what caused the Hawaiian Hot Spot. I gave the usual response about a plume rising up through the asthenosphere and creating a large magma chamber at the contact point between the lithosphere and the rest of the upper mantle...but I was unable to explain what caused the plume to be there in the first place, other than writing it off as an anomaly in the mantle. I would like to answer the student's question, but I am also quite curious myself. I have researched the topic on the internet, but everything I have read avoids speculating on the mechanics behind the plume. Does anyone really have any scientifically sound theories? What is unique about the area that facilitates the formation of the plume in the first place? Any help would be great. I think this is a wonderful resource and will point students here when they have a question they can't find an answer to from their own research. Thanks, Michael
