[1] An independent 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. All three data sets were examined to determine whether a relationship existed between them and if the results of such a study could be used to develop methodology for identifying future geophysical events. The preliminary results from the study have shown that there exists a strong correlation between the solar activity that causes climate changes and the Earth’s largest seismic and volcanic events. The impressive degree of correlation for global volcanic activity (>80.6%) and for the largest USA earthquakes (100% of the top 7 most powerful) vs. solar activity lows provides a basis for future estimates of the time periods and magnitudes for the largest volcanic and seismic events many decades in advance. Finally, the coincidence of the Centennial and Bi-Centennial cycles of the RC Theory showed unmistakable relationships to these largest geophysical events. The use of such a tool may provide a new and valuable method for protection of people and property located in and around high risk geologic zones. Further, a significantly increased risk is indicated during the next 20 years for volcanic and earthquake events of historic scale. Citation: Casey, John. L.
