摘要

The recent paper "Sigma: Issues, Insights, and Challenges" by Strasser et al. (2009) provided an excellent review of the complexity and dependency of the standard deviation of ground motion, as well as the difficulty in reducing it. Strasser et al. (2009) concluded that "the value of has remained fairly stable over the past 40 years," although there have been systematic efforts to reduce it (Atkinson and Boore 2003; Abrahamson and Silva 2008; Strasser et al. 2008). In other words, Strasser et al. (2009) showed that the prospects of reducing are hopeless, even though the authors may still believe that "there is some hope to achieve reductions in , although the process may be labor-intensive." As stated by Strasser et al. (2009), their "attempt is made to identify the more promising approaches for reduction of ." Their paper is not worth a single comment if is simply a statistical issue or personal belief. As stated by Strasser et al. (2009), however, "the effort involved [reducing ] is likely to be worthwhile in the context of seismic hazard analysis." Their paper surely deserves a comment in the context of seismic hazard analysis, modern probabilistic seismic hazard analysis (PSHA) in particular, because the implications for society are far reaching, from seismic design of nuclear power plants, buildings, and bridges to earthquake insurance premiums
