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...

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...

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...

In probabilistic seismic hazard analysis, one wants to calculate the probability of exceedance of a certain shaking level at a particular site. This requires a good understanding of the parameters that can influence seismic ground-motions. Bayesian networks are used to investigate the probabilistic dependencies between several parameters of the groundmotion domain. Problems specific to the doma...

Golsar is located in north-west of Rasht the capital city of Guilan province. This region, according to standards 2800, is identified among the regions with relatively high risk of earthquake. A set of historical and instrumental seismicity data used in radius of 200 km which covers the period twelveth century until now. Kijko method has been applied for estimating for parameters considering of...

Background: Earthquake-prone regions from the stable continental regions (like Peninsular India) warrant total seismic hazard estimation from possible sources — reservoir induced or tectonic. The Koyna region falls in the so-called stable continental region, though previously considered as aseismic because of its location in the Peninsular India, which was argued to be the continental Shield re...

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...

A probabilistic seismic hazard assessment in terms of Arias intensity is presented for the city of Tehran. Tehran is the capital and the most populated city of Iran. From economical, political and social points of view, Tehran is the most significant city of Iran. Many destructive earthquakes happened in Iran in the last centuries. Historical references indicate that the old city of Rey and the...
