Abstract
Recognizing the complementary nature of probabilistic and scenario-based methods for seismic hazard assessment, this paper addresses the framework to integrate the two methods to exploit their advantages for better practice of seismic design and risk management. Advantages, disadvantages, and technical challenges to overcome in each method have been enumerated based on the current state-of-the-art. Post-events examination of the two methods has been made to compare their performance on evaluation of peak seismic intensities in recent major earthquakes in Japan. Toward the advanced seismic hazard assessment, technical exchanges between probabilistic and scenariobased approaches in terms of data and methodologies, as well as their results, are strongly suggested.
