We investigate, through the damage spreading method, the correlation length associated with the two-point correlation function between damage #uctuations, and the damage susceptibility of the square-lattice three-state Potts ferromagnet. We 7nd that both quantities tend to diverge at the damage transition. These results can be interpreted as a 7rst evidence of a possible #uctuation?dissipation-like relation between damage quantities in this model.
