A small-scale resistivity monitor along the San Andreas fault at Melendy Ranch, California, was unable to detect resistivity variations associated with fault creep. No resistivity variations which could be attributed to creep activity were detected, even when sensitivities of 0.005% were employed. The absence of a creep-associated resistivity change is attributed to the electrical behavior of clay during stressing and to the narrowness of the creep zone compared to the measurement geometry.
