Abstract
In this paper, we studied the relationship between sunspots numbers (SNs), solar 10.7 cm radio flux (SRF), solar irradiance (SI), solar proton events (SPEs) and local earthquakes. The location of the study is selected in Iran area and all earthquakes data chosen for M≥ 4 from 1970 to 2010. The study reveals the following conclusions: (i) The total number of local earthquakes in maximum years of solar activities is greater than the minimum years of solar activities from 1964 to 2010, (ii) The total local earthquakes frequency (EF) in the maximum period of solar activities is very close to the maximum annual means of sunspots numbers, (iii) The total local EF in the maximum period of solar activity is very close to the maximum annual means of SPE with negative correlation coefficient, (iv) The local earthquakes in the minimum period of solar activities is very close to the minimum annual means of sunspots numbers with negative correlation and (v) The local earthquake in the minimum period of solar activities is very near to SRF with negative correlation. Key words: Solar activities, sunspots, solar proton events, solar irradiance, earthquake.
