Jane, we had that show on but I'd seen it before so did not pay much attention. I guess I have not run into anything on whether the interior magnetic field of the earth has anything to do with quakes. At the surface though, what I was talking about was the magnetic field of the earth caused by the interior...as it is modified by external effects, causing a geo-magnetic storm...I'm not sure how the magnetic field fluctuates ar 10 or 20 k depth compared to at the surface where it is measured....
