Intensive researches in seismology and earthquake engineering are ongoing in Korea since the mid 1990s.This paper summarizes recent R&D; results regarding the improvement of earthquake catalog, seismicityand tectonics, ground motion, and PSHA methodology. The effect of the R&D; results on the seismichazard was studied for the Ulchin NPP site. Results showed much improvement in the...

As for any model/theory, a probabilistic seismic hazard analysis (PSHA) model is best tested by comparing its predictions with observations that are independent, e.g. which have not been used for creating the model. Arguably, the most valuable information in the context of seismic hazard analysis is information on long-term hazard, namely maximum intensities (or magnitudes) occuring over time i...

This paper presents results from a seismic vulnerability analysis of the components of hydropower systems in Canada. A number of dams and their associated components (hydropower plants, switchyards, transmission towers, and supplementary equipment) at selected locations in western and eastern Canada were analyzed in the study. The seismic vulnerability for a given hydropower component was estim...

A comprehensive program for the evaluation and enhancement of seismic safety of the Paks Nuclear Power Plant was started in 1993 and now is in progress. In the first two years of the program the urgent and quickly realizable fixes were performed, seismic instrumentation was installed, and a procedure was elaborated for the activities to be performed after a possible earthquake. Re-evaluation of...

Seismic hazard analysis is performed for a representative zone in Peru, including the city of Cusco, the citadel of Machupicchu and the archeological complex of Choquequirao, constituting the area with important Inca heritage. This is considered to be the first step towards developing a rational approach to seismic risk analysis of the Inca’s architectural heritage. An evaluation of the vulnera...

 Large-scale subsurface fluid injection has the potential to trigger earthquakes. In addition to seismic hazard, reactivation of faults and fractures during CO2 injection has the potential to compromise storage integrity. These risks need to be taken into account when selecting potential carbon capture and storage (CCS) sites.  Deployment of seismometers at current large-scale CCS projects (m...
