AbstractPredicting the peak ground velocity of vibrations is essential to blast mining operations in order to design the charge weights so as not to exceed certain thresholds that prevent damage to buildings and other infrastructure. The problem is usually marred by a large scatter of observed peak ground velocity due to unknown complexities of seismic
