In our study, we contribute one another connection between geophysics and planetary science by investigating influence of Solar Dipole field (SDF) and frequency of Earthquake’s occurence. First, during period from solar maximum at 2000 to solar maximum at 2012, we compare variations of Number of World’s Earthqaukes (NEQKs) , Solar Dipole (SDF) with equatorial (E-SDF) and axial (A-SDF)components which contribute to of Interplanetary Magnetic Field (IMF). Then, to describe diverging of outer core leading to earthquake, we apply a model of spherical shell composed of co-axial circular areas of infinatisimal thickness. The largest of them surrounds equatorial plane. The shell contains bulk of outer core’s conductive liquid. According to our model, we focus on total contributions from forces applied by Axial and Equatorial Dipole Fields, of Earth (A-EDF and E-EDF) along the radial distance, to act on azimuthal elecrical flow and convectional elecrical flows, respectively. Influence of Coriolis force decreases whenever the force acting on the convectional flow is effective to push the outer core diverges toward mantle to trigger an earthquake . Plotting of Number of Geomagnetic Storms (N-GMS) per Year is considered, the variations in N-GMS, and the strengths of A-SDF and E-SDF, are seen to be connected with the variations in N-WEQKs, throughout the solar storms, for the period of interest. During rising phase from 2000 to 20003, as the strength of SDF with dominant components of west to east oriented (WE ) E-SDF , which contributes mainly to IMF, increases. As the strength of WE IMF, increases, number of solar storms increases. The increasing number of solar storms , which distort the EDF with components of EW E-EDF and northward (NW) Axial EDF (A-EDF), results in decsending N-WEQKs . During rising phase from 2003 to 2009, as the strength of SDF with dominant components of west to east oriented (WE) E-SDF , which contributes mainly to IMF , decreases, the strength of WE IMF and number of solar storms decrease and leads to increase in N-WEQKs . During rising phase from 2009 to 2011, as the strength of SDF with dominant components of southward (SW ) SADF , which contributes mainly to IMF, decreases. leads to more effective NW A-EDF which results in ascending N-WEQKs.D uring rising phase from 2011 to 2012, the strength of SDF with dominant east to west oriented (EW ) SEDF , which contributes mainly to IMF , increases. The increasing strength of EW IMF leads to less effective NW A-EDF. Hence, N-WEQKs is reduced. To conclude, our study shows that better modeling and forecasting of earthquakes could be done throughout the conditions in Earth-Sun system, instead of conditions just on Earth.
