J. Tuzo Wilson

J. Tuzo Wilson is a Canadian geoghysicist who discovrered a theory beyond the hotspot volcanoes. He had stated that volcanism has been active for a long period of time in a certain locations around the world, such as Hawaii. This could only happen if hotspots existed below the plates that would provide high heat energy to continue the volcanism.  As one island volcano becomes extinct, another develops over the hotspot, and the cycle is repeated. This process of volcano growth and death, over many millions of years, has left a long trail of volcanic islands and seamounts across the Pacific Ocean floor.
