This book is outcome of my research on Msc in Structural Engineering. Microzonation is the procedure of estimating the total seismic hazard from the ground taking into account the effect of local site conditions.. This research is used to draw a microzonation map of kathmandu valley using the peak ground acceleration after amplification of soil.The Kathmandu valley is underlain by thick lacustrine quaternary deposits which are susceptible to ground motion amplification. The realistic modeling of seismic ground response analysis is very important in the seismic microzonation. This however greatly depends on the availability of detailed subsurface geological and geotechnical information as well as strong ground motion records. As there is only limited borehole data on depth to bedrock, geophysical surveys and geotechnical properties of the soil type of Kathmandu valley, a one dimensional seismic response modeling software could only be done based on the number of assumptions for geotechnical parameters and soil depth.Altogether 14 boreholes profile from different sites of the Kathmandu valley was used for the seismic response analysis.
