ABSTRACT

We developed a statistical study analyzing global seismicity enhancement and its variation overtwenty years. X-flares sometimes occur in conjunction with Coronal Mass Ejections (CME),which make their connection with the Earth’s magnetosphere stronger. The preliminary study divided the Earth into seven regions determined by longitude and latitude, and nine levels of depth valid for most locations in the Pacific area. The results showed that X beams influenced seismicity in terrestrial localities, mainly high magnitude earthquakes occurring below the crust at 70 km. These internal enhancements happen without the presence of any external forces such as studied in Solar Speed Winds. Nevertheless, those variations are perceptible in the presence of intense X flares and CME and less observed in the periods during which flares were absent. Two cases of high magnitude earthquakes in recent years are analyzed, and the extreme external conditions of those events fit with this theory.
