The article presents a study on the history of volcanism at a shallow ice core from Dome A in East Antarctica from 840 before Christ (B.C.) to 1998. It cites ice cores from polar regions as the best medium for assessing the impact of past volcanism on the climate of the world. Examination of the DA2005 ice core sample shows that the total number of volcanic eruptions within the study period identified in the top 100.42 meters (m) were 78 volcanic eruptions. Findings show that the largest volcanic eruption seen in the ice core occurred in 425 BC.
