A new theory proposes that volcanoes magma source is not from deep under the Earths surface but much closer. The study suggest that volcanic magma is from the Earths upper Mantle, the asthenosphere layer.
Don Anderson (Caltech) and Scott King (Virginia Tech) propose that the heat and magma needed for a volcano is found in the asthenosphere layer, with the magma coming from as near as 50 miles below the surface and down to 125 miles deep.

Their idea also challenges accepted plate tectonics theory amongst other geology theories.
“For nearly 40 years there has been a debate over a theory that volcanic island chains, such as Hawaii, have been formed by the interaction between plates at the surface and plumes of hot material that rise from the core-mantle boundary nearly 1,800 miles below the Earth’s surface,” King said. “Our paper shows that a hot layer beneath the plates may explain the origin of mid-plate volcanoes without resorting to deep conduits from halfway to the center of the Earth.”

Volcanoes and the EU theory
The Electric Universe theory has been suggesting that volcanoes are an electric phenomena, powered by electrical currents or events. These would be at or near the Earths surface, similar to what is now being proposed.
An electrical source for the heat and energy needed for a Volcano and its magma would also help to explain strange electromagnetic phenomena before, during and after volcanic explosions – such as volcano lightning.
