Surface Wave Induced Ground Particles Vibration At Eastern And Western Ethiopian Plateaus

Blasting of explosives on or under the surface of the earth always induce seismicrnwave of all kinds that propagate in every direction away from the point of explosions. Inrnthe course of seismic propagation in ground medium, ground vibration will occur thatrnmay result distraction on man made structures unless appropriate seismic method ofrnpre-Explosion ground vibration prediction are made to determine the size of explosivernenergy to be applied and relative distance of shot and man made structures arernestimated.rnIn this research ground vibration prediction is made on the West and EastrnEthiopian plateau from surface wave recordings from two 900 kg and 1900 kg andrn1100 Kg explosions made at Gohatsion and Gebre Guracha and Kula areas and peakrnground vibration measurement made by Guralp 6TD seismic recorder at different pointsrnalong EAGEAL profile 1.rnAs a result, the measured PPV at the western plateau is over determined by thernoriard minimum prediction formula at large distances while at the Eastern plateau thernobserved value is greater than the prediction obtained from the Oriard maximumrnprediction formula.
