The regression coefficient for the site term has a strong correlation with the bedrock depth at each site in the Kathmandu Valley. Therefore, a new GMPE applicable to the whole Kathmandu Valley in the long-period range of 1-10 s was generalized using the bedrock depth as a parameter. We applied this GMPE to the largest aftershock. Consequently, at each sedimentary station, the residuals of the predicted value by GMPE are smaller than those predicted by the existing GMPE, and the peaks of the observed response spectra are reproduced well.ElsevierJournal Articleapplication/pdfapplication/zipapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenttext/xmlhttp://hdl.handle.net/2115/78975https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/78975/1/1-s2.0-S0267726119311431-main.pdfhttps://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/78975/2/1-s2.0-S0267726119311431-mmc1.ziphttps://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/78975/3/1-s2.0-S0267726119311431-mmc2.docxhttps://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/78975/4/1-s2.0-S0267726119311431-mmc3.xml0267-7261AA1053934XSoil Dynamics and Earthquake Engineering1351062082020-08enginfo:doi/10.1016/j.soildyn.2020.106208https://creativecommons.org/licenses/by-nc-nd/4.0/publisher
