what is a circulating current of magma
It is boiling hot melted rock, moving about in some circular flow.
Apparently there are places underground where magma (molten basalt above 1000 C) circulates in a flow loop, up and down, without reaching the surface. One such place is below a volcano in Nicaragua. There may be others below Flagstaff, AZ, Yellowstone, Hawaii, and the active and dormant Cascade volcanoes of the western US (Lassen; St. Helens; Baker). There is interest in exploring these regions for geothermal energy.
