> It's still referred to as one hotspot, but there may be separate mantle plumes in close proximity.

Does it need to be separate plumes or can it be bifurcation of a single plume as it passes through the crust?

I don't know the answer to this question myself, and I suspect our knowledge of hotspots is poor enough that no one can answer this question definitively.
