Abstract
The locations of volcanic islands may be controlled by thin or extending parts of the
lithosphere over a partially molten asthenosphere (1, 2), by edge effects near the boundaries of
thick cratonic lithosphere (3), or by narrow jets of hot mantle rising from deep within the mantle
(4-6). Many hotspots are found on or near ridges, at lithospheric discontinuities, or in
