TL;DR: In this article, the authors reviewed the seismotectonic setting and regional seismicity in Nepal and analyzes available aftershock data and ground motion data to gain deeper understanding of the observed earthquake damage in Nepal.

TL;DR: This research presented in this article is supported by King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia, by Grants BAS/1/1339-01-1 and URF/ 1/2160-01 -01-01.

TL;DR: In this paper, the authors investigated the correlation structure of regression residuals from the prediction equation and found that the residuals of ground motion parameters at different vibration periods are more strongly correlated than intra-event and total residuals with zero separation distance.

TL;DR: In this article, the effects of aftershocks by using real as well as artificially generated mainshock-aftershock sequences were investigated, and the results from nonlinear dynamic analysis of inelastic single-degree-of-freedom systems using real and artificial sequences indicate that the incremental effects on peak ductility demand using real sequences are relatively minor and that peak ductile demand estimates based on the generalized Omori's law are greater in the upper tail than those for the real sequences.

TL;DR: In this article, a simulation-based framework for assessing seismic risk of spatially distributed buildings is developed by taking the spatial correlation of seismic excitations into account, and the assignment of the partial correlation is based on a recently developed spatial correlation model and the sets of hypothetical buildings mimic existing building stocks in downtown Vancouver.
