The paper presents the variation of variable component of coronal index for two period 1950–1962 and 1963–2014 and its association with major earthquakes (magnitude ≥6.0 Richter scale) for the same two periods is also offered. Analysis shows that frequency of major earthquake increases with the decrease in variable component of coronal index and vice versa. Possible explanation is also presented. © 2016, Indian Association for the Cultivation of Science.
