Results of previous studies have pointed to a statistically significant relationship between the ionospheric, ie. atmospheric disturbances and earthquakes. Also, numerous previous studies concerning the relationship between the sun's activity and disturbances in the atmosphere have been taken into consideration. Based on these indicators, we tried to determine the possible existence of a causative-effective connection between processes on the sun and the earthquake that occurred on 03 November 2010 near Kraljevo (Serbia). Based on theoretical considerations, a new model is proposed that suggests the occurrence of trigger pulse. The results have shown that at statistically more significant number of samples it would be necessary to determine potential regularity in the changes of the parameters of the interplanetary magnetic field (IMF), that is solar wind components (SW) a few days before and after the occurrence of strong earthquakes.
