Simulation of the 1934 earthquake in Kathmandu, Nepal

Abstract In this study, utilizing appropriate target spectra and a special envelope function, an artificial time history is generated for the major earthquakes of 1934 and 2015 A.D. The peak ground acceleration (PGA), mean time period, predominant period, significant duration, response spectra, and Fourier spectra of the 2015 earthquake are obtained from the generated time history and compared to those of the recorded earthquake. The maximum PGA derived from the simulation and the PGA derived from the damage-based MMI scale are compared for the earthquake of 1934. These earthquakes' significant duration is also compared with other subduction zone earthquakes. Compared to other subduction zone earthquakes, Nepal's earthquakes have a longer significant duration.
