Whose work first showed that volcanic islands can form above hotspots far from plate boundaries?
Quick Answer
J. Tuzo Wilson is closely associated with the hotspot idea, developed in the 1960s. It explained chains like Hawaii as the result of a moving plate passing over a stationary mantle plume.
The Full Story
J. Tuzo Wilson helped explain volcanic island chains by proposing a hotspot model. In this framework, a relatively stationary source of heat in the mantle creates volcanoes as a tectonic plate moves over it. The Hawaiian Islands are the classic example, with older islands farther from the active hotspot. This idea helped show that not all volcanoes belong to plate boundaries. It remains a major concept in understanding intraplate volcanism.
