Many proposed hotspots, including isolated structures and the active portions, or inferred ends, of seamount chains, do not have significant swells, substantial magmatic output, or tomographic anomalies. A hotspot catalog, as opposed to a volcano catalog, is therefore subjective. Recent lists of those purported to be underlain by deep mantle plumes disagree strongly.
