Abstract: The features of peak ground velocity (PGV) attenuation near the fault were considered. It has been established that similar to the peak ground acceleration (PGA) the peak ground velocity (PGV) for earthquakes with different magnitudes (M) are well scaled by fitting data along the distance (R) axis, and not along the amplitude one. According to empirical amplitude distribution there are four zones with different attenuation near the fault. The features of each zone have been studied. The empirical attenuation relations of PGV for every zone have been studied separately. The new uniform empirical attenuation law for PGV has been developed.
