Abstract
We argue that fracture surfaces may exhibit anomalous dynamic scaling properties akin to what occurs in some models of kinetic roughening. W e determine the complete scaling behavior of the local fluctuations of a brittle fracture in a granite block from experimental data. We obta in a global roughness exponent chi=1.2 which differs from the local on e, chi(loc)=79. Implications on fracture physics are discussed.
