Abstract
Superposition of the polar shifts computed for 234 large earthquakes (Ms ≥ 7.8) that occurred between the years 1901 and 1970 yields a synthetic curve that closely resembles the observed pattern of variations of the Chandler wobble during the same period. We conclude that earthquakes represent the major factor in the wobble excitation.
