Member Since 1982
Norm A. Abrahamson
Adjunct professor, University of California Berkeley
Dr. Abrahamson is an internationally known expert in seismic hazard and risk analyses with a focus on moving research in the earthquake sciences to engineering practice. He has developed ground-motion models used in seismic hazard analysis throughout the world. His current focus is on the development of non-ergodic ground-motion models that merge empirical ground-motion data , 3-D simulations, and macrointensity data as well as the implementation of these models into seismic hazard programs.
