"Solar flares and magnetic storms belong to a set of phenomena known collectively as "space weather". Technological systems and the activities of modern civilization can be affected by changing space-weather conditions. However, it has never been demonstrated that there is a causal relationship between space weather and earthquakes. Indeed, over the course of the Sun's 11-year variable cycle, the occurrence of flares and magnetic storms waxes and wanes, but earthquakes occur without any such 11-year variability. Since earthquakes are driven by processes in the Earth's interior, they would occur even if solar flares and magnetic storms were to somehow cease occurring."
This makes sense to me. The variability of the Sun should at least correlate with earthquake activity, the fact that it does not leads me to realize that it is not causative either.
That leads me to my next point. Why push this idea? It is not about science at all I think. Its about money, its about leading a fear-agenda to make sales of a website. Be afraid! Buy my stuff. Its classic.
