SILBERGLEIT, Virginia Mabel  and  LAROCCA, Patricia Alejandra. Statistics of sunspots and earthquakes in Chile. Geoacta [online]. 2014, vol.39, n.2, pp.44-53. ISSN 1852-7744.

Solar activity influences the geosystem and this activity could be studied by sunspots. In this paper a statistical study of sunspots and the seismic moment of earthquakes with epicenters in Chile during the years 1906 to 2011 is done. We study periodograms in which periodicities of about 11 and 22 years for the Sun and between 2.4 and 8.5 years; 11-14 and 26.2 years for the earthquake magnitude are observed. The correlation coefficient between the above mentioned data was C = 0.6. For both data series the Weibull function showed good fits.
