Yeas, and Haarp can control the weather and be used for mind control. It's so versatile!
I suspect its military applications are more mundane than some would try to lead us to believe.
The coupling between geomagnetic fields and ionospheric currents ain't so great, there have been some reports on ionospheric indicators or precursors correlating to Earthquakes but how well do they correlate if at all and no indication that it can happen in reverse and effect an Earthquake by a relatively mild excitation of the ionosphere (in natural terms).
