Abstract
TELESEISMIC residuals of the Matsushiro seismic station clearly indicate a decrease in P-wave velocity underneath this station beginning three years before the Matsushiro earthquake swarm of 1965. This is the first instance where premonitory velocity changes have been observed before strike slip faulting1,2. It is concluded that P-wave residuals provide another means for assessment of the earthquake risk near seismic stations.
