Relationship between Seismicity and Solar Activities during Solar Cycle 22

The relations between sunspot numbers and earthquakes (M ? 5) and (M ? 8), solar 10.7 cm radio flux and earthquakes, solar proton events and earthquakes, sunspots area and earthquakes during solar cycle 22, from 1986 to 1996 have been analyzed in this paper. It has been found that (1) there is an inverse relation between solar activity and earthquakes activity for M ? 5 during solar cycle 22. (2) There is a direct relation between solar activity and earthquakes activity for M ? 8 during the maximum of solar cycle 22 and an inverse relation between both at the descending phase of the cycle.
