摘      要：Understanding the parameters of PGA （peak ground acceleration） is very important for seismic hazard mitigation and environmental planning in Mandalay City, Myanmar. In this study, fifty SPTs （Standard Penetration Tests） measurement data were collected in Mandalay City, for calculating average shear velocity Vs30, which will be used in seismic microzonation mapping. The shear wave velocity Vs30 of the top layer is Vs30 〈 220 m/s. The ground motion characteristic was estimated by means of the predominant periods and linear magnification factors obtained using the multiple reflection analysis. The highest potential zone of seismic hazard mostly locates the north western marginal part of Mandalay city, in the proximal portion to the dextral Sagaing fault.
