～ L^1.21 and ～ Lfor p = pc and p > pc, respectively. The region of the tracer dispersion is wide when p = pc and rather narrowwhen p > pc. Numerical simulations indicate that the transverse fluctuation has the same scale as the correlationlength of the percolation structure, which is a system of size L when p = pc and is constant for a large systemsize L when p > pc. It is also shown that the travelling time has a power-law behaviour when p = pc.
