Abstract
The viscous damping of fracton vibrations in 2D percolation clusters i s computed. It is found that the anomalous damping is due to the local irregular distribution of the vibration amplitudes. There exists a lo calization of the damping within the usual localization of fractons. T his effect is strongly enhanced by nonlinear dissipation. This is the first evidence of the damping power of fractal structures.
