An investigation of the effects of disorder on the modes of vibration of nearly periodic
structures is presented. It is shown that, in structures with close eigenvalues, small structural irregularities result in both strong localization of the mode shapes and abrupt veering away, or mutual repulsion, of the loci of the eigenvalues when these are plotted against
a parameter representing the disorder in the system
