Close Correlation Between Solar and Seismic Activities

Authors: A. M. Eigenson

Large earthquakes in the last 260 years are compared with the epochs of minima of 11-year cycles of Solar activity. We use the data from 352 earthquakes of magnitude 7 and larger. Close correlation between earthquakes and the minima of solar cycles is shown, with the correlation coefficient of 0.9998. Maximal number of earthquakes shows 11-year periodicity. The number of earthquakes increases with time and reaches its currently largest number in the last Solar cycles, corresponding to the decrease of Solar activity in cycle 23. Furthermore, we analyse the data of large volcanic eruptions in the last 400 years. Similarly to earthquakes, the volcanic eruptions show the correlation with the minima of Solar activity, with the correlation coefficient of 0.9994. The volcanic eruptions also tend to increase with time, corresponding to the decrease of Solar activity. The found correlation between solar and seismic activities opens the possibility of prognosis because the Solar activity may be predicted for many years forward.
