New Information on the formation of volcanic islands

Reply Fri 15 May, 2020 05:58 pm
What causes the fluctuations that turn mantle-plume volcanic activity on and off, as described in this article about how the previous theory/assumption of single-burst volcanic island formation is now being revised?

What kind of energy and/or gravitational fluctuations could cause an island-forming convection current to taper off and later resume to earlier levels of intensity?
