Using Recent Hurricane Data To Evaluate Prospective Risk Models
January 2009
In mid-December, the former president of a CAT modeling company published a "paper" concluding that "near-term", or conditional risk hurricane models are invalid.

Mr. Campbell's comment on the CEUS attenuation relationship developed by Tavakoli and Pezeshk (2005) using the hybrid empirical method that he published in 2001 and 2003.

Kenneth co-wrote a paper presenting a new empirical ground motion model for PGA, PGV, PGD and 5% damped linear elastic response spectra for periods ranging from 0.01–10s. This paper was submitted to the 14th World Conference on Earthquake Engineering (14WCEE) to be held in Beijing in early October 2008.

"The empirical ground motion model (attenuation relation) presented in this paper represents the culmination of a four-year multidisciplinary study sponsored by the Pacific Earthquake Engineering Research Center (PEER) and referred to as the Next Generation Attenuation (NGA) Ground Motion Project (Power et al. 2008, this volume)."

Kenneth co-wrote a paper comparing the data sets, model parameterizations, use of analytical model constrains, and the resulting ground motions (median and aleatory variability) from the five NGA models.
