At http://spaceweather.com March 12th, it is said it is just a coincidence that the earthquake in Japan coincided with a geomagnetic storm – in case anyone was thinking otherwise. Earthquakes occur without geomagnetic activity and vice versa – but does that put paid to the possibility?
In contrast to NASA, Piers Corbyn at www.weatheraction/com/displayarticle.asp?a=325&c=5 claims there is a definite connection between major solar flares and seismic activity on earth. He warned after the recent New Zealand quake, which also coincided with a solar flare, that other big earthquakes were likely to strike – and today he is saying this situation is likely to continue for the next two years.
