Webinar Tsukuba University & UGA #4 - Territories & Risks (2)

Abstract
The estimation of seismic damages at an urban scale  is challenging for several reasons. First, commonly used methodologies for seismic damage estimation rarely take into account the local site effects at the building-level. Second,  in countries with limited census data and incomplete building datasets, the lack of comprehensive data on the building stock  and their taxonomy further increases the complexity of assessing possible earthquake consequences at an urban scale. We will present how we tackle these challenges in the city of Beirut in Lebanon,  one of the most exposed Middle-East countries to seismic risk.

Prof. Cecile Cornou is Director of Research at the Institut de Recherche pour le Développement (IRD). She works at Grenoble Alpes University's ISTerre laboratory, in the Geophysics of Seismic and Gravity Hazards research team. She is scientific co-leader of the RISK Institute project at Grenoble Alpes University and a member of the Telluric Crisis and risks cluster.
Her work focuses on :

• Seismic hazard, with a particular focus on site effects
• Seismic noise for site effects and site characterization  
• Seismic risk modeling in urban environments

Advancements in Seismic Hazard Assessment and Strong Motion Prediction Methods

Abstract
In order to contribute to the creation of National Seismic Hazard Maps for Japan, we have been conducting research on probabilistic seismic hazard analysis and strong ground motion prediction methodologies to create seismic hazard maps for specific seismic faults. Additionally, we have been working on modeling subsurface velocity structures and developing simulation methods based on physical models. We continue to refine these methods based on lessons learned from the Great East Japan Earthquake and the Kumamoto Earthquake. We will present the progress of seismic hazard assessment and strong ground motion prediction methods over the past 20 years and discuss future challenges.
