Invitation to SS24.3 Special Session on GMPEs at the 15WCEE in Lisbon

Forwarded announcement from Luis Dalguer, ETH-Zurich:

Dear SCEC colleagues attending the 15WCEE next week,

I would like to draw your attention to the SS24.3 Special session (description below and program in attachments) we are organizing during the 15WCEE. This session aims to discuss the feasibility of incorporating physics-based rupture advancements into GMPEs, the current stage and future directions.

Date: September 24, 2012
Time: 17h15 – 19h15
Room: P3b

Please be free to forward this announcement to people/groups that may be interested to attend.

Looking forwards to see you in Lisbon.

All the best,

Luis Angel

SS24.3 SPECIAL SESSION at the 15WCEE

Title: Toward Improvement of GMPEs Incorporating Physic-Based Ground Motion Simulations

Summary:
Current empirical ground motion prediction equations (GMPE) may fail for the prediction of near-source ground motion and its spatial variability for use in seismic hazard and risk assessment and earthquake-resistant structural design. That is because these GMPE are based solely on recorded data which are sparse in the near field. On the other hand, recent development of numerical simulations of earthquakes based on physics of the causative source rupture and wave propagation have contributed to substantial advances in our understanding of different aspects related to the earthquake mechanism and near source ground motion. These models have greater potential for identifying and predicting the variability of near-source ground dominated by the source and/or geological effects. An ad-hoc alternative to fill the lack of GMPE is the use of physics based numerical models to build “hybrid physics-based GMPE”.This session aims to discuss the feasibility of incorporating physics-based rupture advancements into GMPEs, the current stage and future directions. It is supported on invited presentations specially dedicated to it. Key speakers are Norm Abrahamson (UC Berkeley/Pacific Gas & Electric Co), Gail Atkinson (University of Western Ontario) and Saburoh Midorikawa (Tokyo Institute of Technology).
