Long-term evidence for the association of earthquakes with the excitation of the Chandler Wobble

A means for comparing yearly earthquake counts with the ILS-IPMS polar data is devised. The comparison supports the theory of Mansinha and Smylie that earthquakes are associated with the free (Chandler) wobble of the earth's pole. There is some indication, however, that earthquakes themselves are not the source of wobble excitation but are instead a parallel effect.
