In March last year a preliminary study was published from the Space and Science research centre in Florida.
A review of historical records was performed for 350 years of global volcanic activity (1650-2009) and seismic (earthquake) activity for the past 300 years (1700 to 2009) within the continental United States and then compared to the Sun's record of sunspots as a measure of solar activity.
According to this study, there exists a strong correlation between solar activity and the Earth's largest seismic and volcanic events.
They found an impressive degree of correlation for global volcanic activity (>80.6%) and for the largest USA earthquakes (100% of the top 7 most powerful) versus solar activity lows.
According to another study, published in Earth and Planetary Science letters, solar activity, as indicated by sunspots, radio noise and geomagnetic indices, plays a significant but by no means exclusive role in the triggering of earthquakes, with maximum quake frequency occurring at times of moderately high and fluctuating solar activity - which is what we have seen in the last few weeks. |
