Simulation of the 1934 Nepal–Bihar earthquake in Kathmandu

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 simulated time history These ground motion parameters of simulated earthquake are compared to those of the recorded earthquake of 2015. For the earthquake of 1934 A.D., the maximum PGA derived from the simulation and the PGA derived from the damage-based MMI scale are compared. 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.
