The average P residual increased by 0.4 s 1.2 yr before the ML =5.7 Garm earthquake of March 22, 1969. This is interpreted to indicate a decrease in the P velocity by approximately 10-20% in the local crust. The P wave precursor time is slightly shorter than that indicated by a preferred alignment of the compression axes and by a decrease in local seismicity (Nersesov et al., 1973). Barsukov (1972) reported a decrease of apparent resistivity 0.6 yr before the same event. All precursor observations were obtained within a radius of 25 km of the epicenter and outside by 6 by 10 km aftershock zone. The precursor volume must have exceeded the source dimensions by a factor of 5.
