Estimating ground motion levels in earthquake damage investigations: a framework for forensic engineering seismology
by Julian J. Bommer; Peter J. Stafford
International Journal of Forensic Engineering (IJFE), Vol. 1, No. 1, 2012

Abstract: Earthquake-resistant design matches performance targets of structures and facilities with defined levels of ground shaking. Structural failure in an earthquake may result from higher ground motions or from poor design and construction. In legal disputes in such circumstances experts are required to infer the ground-motion levels at the site, if there are no ground-motion recordings. The proposed framework proposed requires a common database of models and observations, with each expert entitled to make technically defensible assessments of their individual credibility. Bayesian updating is then used by each expert to estimate the ground-motion level satisfying all of the accepted evidence.
