Estimation of Strong Ground Motion Parameters in Amarapura Township, Mandalay Region

Amarapura Township, Mandalay Region is located very closed to the most active dextral Sagaing Fault in Myanmar. In the historical record, several earthquakes happened in and around Mandalay, Amarapura, Innwa, Sagaing region from the beginning of the year of 1400. Even a moderately strong earthquake may cause great loss of lives and property damage. An evaluation of the seismic risk of urban areas cannot neglect the variability of the ground vibration due to site amplification and the induced effects, such as soil liquefaction etc. We conducted 21-sites of microtremor measurement to gain a representative determination of the underground structures and predominant frequency in Amarapura Township. These parameters are required for seismic resistant design of structures. The very highest potential zone of seismic hazard mainly locates the western marginal part of Amarapura Township, in the proximal portion to the dextral Sagaing Fault
