Japan earthquake cause?

solar winds from the sun causes geomagnetic thermal activity?, global warming?, or was it H.A.A.R.P - WAS THERE A SIGNAL THAT COULD BE INTERCEPTED COMING FROM H.A.A.R.P?, no person respond without some evidentiary proof, proof that there was a monitor that either picked up a signal that it was turned on or that someone was indeed monitoring haarp's signal and that it definately was not turned on just before the quake.
