Abstract

In this study, for the first time, we compared the annual magnetic Ap index, taken from original sources, from 1844 to the present day [Svalgaard,2014], with:

i) sixteen large volcanic eruptions of index VEI5 + recorded by, Smithsonian Institute (Global Volcanism Program), ii) three sets of the volcanic aerosols data [Ammann et.al,2003][Gao;Chaochao;Alan Robock;Caspar Ammann, 2008][Traufetter et.al,2004] and iii) eight major earthquakes of a magnitude between 8.7<M<9.5, which occurred from 1900 to the present.
