Today analyzing seismicity hazard urban different areas is critical and inevitable due to develop and to expand cities in seismically active zones and naturally, the hazard because the earthquake is more in the bigger cities and the necessity to consider these hazards would be increased. Expanding the cities in Iran seismically active zones caused to be necessary to analyze earthquake hazard. B...

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...
