Electric Volcanoes

Authors: Charles L. Chandler

Significant anomalies in the fundamental conception of the driving forces in volcanoes are explored. It is unlikely that felsic magma would have the thermal energy necessary to melt its way through the thickest aspect of the crust above a subduction zone, without an unidentified heat source. And while mafic magma such as at Kīlauea flows through the much thinner oceanic crust, this has been explained as the outflow from a mantle plume, even though the seamount chain began in a subduction zone that is older that the postulated plume, and which is mutually exclusive with it. Hence subduction volcanoes are the primary riddle. A new heat source is considered: resistive heating from telluric currents. The significance is that it might be possible to prevent cataclysmic eruptions, such as at Yellowstone, by shunting the current into a new path, using a conductive borehole some distance away from Yellowstone, which would remove the resistive heating and thereby relax the pressure in the existing chamber.
