  We present numerical data of the height-height correlation function and of
the avalanche size distribution for the three dimensional Toom interface. The
height-height correlation function behaves samely as the interfacial
fluctuation width, which diverges logarithmically with space and time for both
unbiased and biased cases. The avalanche size defined by the number of changing
sites caused by a single noise process, exhibits an exponentially decaying
distribution, which is in contrast to power-law distributions appearing in
typical self-organized critical phenomena. We also generalize the Toom model
into arbitrary dimensions.
